Hi fellas here's another question for you all.

(Driver A - Tesla - Right lane - Orange MS Paint Line)
(Driver B - Mustang - Left lane - Blue MS Paint Line)

Driver A enters roundabout (two lanes) from right most lane with intention to turn right.
Driver B enters roundabout from left lane also indicates to turn right.

Lane markings show

  • Right lane must only turn right
  • Left lane can go straight or right.

Driver B makes a uturn throughout the roundabout.
Driver A turns right and in doing so goes through outer most lane in the roundabout.
Driver A's front left impacts Driver's B's side.

So who is at fault?

Edit: Comprehensive insurance claim sent.

      Both. You have to assume motorists are idiots, always, even though it's a tiny percentage, it's enough to cause havoc.

    • tenpercent on 19/05/2025 - 12:14

      A moron was in the right lane, but decided they actually wanted to turn left not right, and drove straight across in front of me to exit.

      Is that not basically what happened here? Driver A from the centre lane turned his/her vehicle left straight across in front of Driver B who was in the outer lane.

      • SlickMick on 20/05/2025 - 08:53

        It is, but this one was premeditated. Driver A sat beside Driver B right across the roundabout before the attack. In my case, it happened in a split second, literally as we entered the roundabout.

  • Caped Baldy on 19/05/2025 - 10:36

    I've seen near misses there but rarely drive from that direction and know I understand why.

    On approach you must indicate right, and turn using the right lane, unless arrows show you can use other lanes to turn right.

    You must give way to all vehicles already on the roundabout.

    You must continue to indicate right as you turn. When you leave, you must indicate left, if practical.

    That said, the diagram only has a right arrow on the right lane.

      does it mean driver B also right? then driver A should watch out before cutting across & exit

      is there such thing both driver at fault?

      • Caped Baldy on 20/05/2025 - 13:28

        is there such thing both driver at fault?

        Yeah there is.

        Actually, there is more info here which I didn't find earlier.

        When making a U-turn, you must:

        have a clear view of approaching traffic
        start your U-turn from the marked lane nearest to the centre of the road
        start your U-turn to the left of the centre of the road if there are no lane markings
        make the turn without obstructing traffic
        give way to vehicles and pedestrians
        indicate before you start to turn.

        After you turn, check your mirrors and blind spots again, indicate, and only pull out when it’s clear and safe.

    Driver A is at fault.

    The right lane wasn’t an exiting lane. You need to safely change into the left lane before reaching the exit you want.

    Sometimes both lanes may exit, but in those cases, the left lane will be an exit-only lane.

    • wannagrababargain on 19/05/2025 - 12:44

      +1, it's like any multi lane Rd. The "Red" line needs to safely change lanes before reaching the exit. It's effectively two manoeuvres. Red driver changed lanes unsafely.

      You're joking right? There's TWO lanes at that exit, for BOTH lanes to exit.

  • GordonD on 19/05/2025 - 10:46

    A roundabout is not one intersection. You have to signal and give way appropriately at each intersection that makes it up.

    The arrows at the intersection where the cars are entering the roundabout is irrelevant in this case, because the collision occurred at the intersection where the cars are leaving the roundabout. What is relevant there is the lane markings there. At that point the vehicle on the left was entitled to stay in its lane and follow the lane markings on its right around the roundabout, and the vehicle on the right crossed the lane markings and so was required to signal and give way to the vehicle on the left. Since it didn't, it was in the wrong when a collision occurred. It should have changed lanes in the roundabout so it was in the correct lane at the exit point. The driver in the left lane should have had the sense to be in the other lane. In that sense both drivers showed poor road sense.

    More sensible lane markings there would have forced the vehicle on the left to either leave the roundabout or signal right and cross the lane markings, putting them in the wrong if a collision occurred there.

    Multilane roundabouts are a nightmare for crashes, because you have to do what the right thing is for what the lane markings are going to say further around the roundabout, before you get to them. So if the roundabout is new to you, or they say something unexpected, you are in the wrong place. And the fact that they are multi-lane because the traffic heavy just makes it harder for someone to be in the right place doing the right thing at the right time. It produces cognitive overload, which is events occurring faster than drivers can process them, which causes crashes.

    In Adelaide its the Britannia roundabout. Used to costs insurance companies a fortune, but they tidied it up a bit. Now it just costs them a small fortune.

    If a roundabout is busy enough that it needs to be multilane, it needs to be replaced with traffic lights.

      Article from 3 years ago lol Apparently the problem with that intersection is it's owned by 3 councils. Considering how much trouble people already have with one council organising things, 3 is obviously always going to be impossible.

      The roundabout design and signage at Homebush DFO is terrible.

      This website says that for u-turns you must start your U-turn from the marked lane nearest to the centre of the road.

      Seems clear to me that the Mustang is in the wrong by this definition.

        I don't even get WHY they thing u should U-turn in this stupid roundabout.
        You can signal L/R but not signal U-turn. They're shit even in suburban mini-bouts where they expect you to read their mind how many loops they're planning.

      Are you seriously suggesting that when the inner lane driver at a roundabout is exiting right, it needs to change lanes INSIDE the roundabout to exit??

        How do you exit right on a roundabout?

        Aren't you technically exiting to the left when you leave a roundabout?

        If you are turning right to exit a roundabout, you might find that you're driving on the wrong side.

  • tsunamisurfer on 19/05/2025 - 11:31

    Let's assume I have this right.

    Driver A = Tesla, on the inside lane of the roundabout, on the right hand side.

    Driver B = Mustang, on the outside lane of the roundabout, on the left hand side.

    I have tried reading others' thoughts but always come back to, you cannot exit a roundabout from the inside lane. Can you imagine the carnage if this were allowable?

    • CaptainJack on 19/05/2025 - 12:44

      It looks like there's two exit lanes, and possibly the mustang was in a must exit lane. Though I may be wrong.

    • GordonD on 19/05/2025 - 12:44

      you cannot exit a roundabout from the inside lane

      Your conclusion is right, but that statement of yours I've quoted isn't always right. You can exit a roundabout from the inside lane if you are not crossing a lane marking. That is the case where the marking between the two lane directs the vehicle in the outside lanes to exit the roundabout. If it is an unbroken line they must exit. If it is broken they have the choice of keeping to the left of it and exiting, or signaling to the right, and changing lanes, giving way to any vehicle on their right. The vehicle on the right can follow the lane marking on its left and exit, or continue around the roundabout.

      I was confused by the roundabouts in Portugal when I visited. They exit from the outside lane so they change lanes in the roundabout per the linked diagram..

    • Some Guy on 20/05/2025 - 17:58

      you cannot exit a roundabout from the inside lane

      Nonsense. Check out the roundabout at the intersection at Sulwood Dr/Athllon Dr in Canberra. Car in the inside lane can exit at exit 2, 3 or 4, ie except the first one which would be a left turn. This is very common. Note the line markings inside the roundabout.

      In the OP's case, in addition to the new arrow on the outside lane (now permitting a right turn from that lane), I expect there would also be markings on the road inside the roundabout guiding the driver to the available exits (2 and 3) and preventing the outside lane driver exiting via exit 4 (ie doing a U turn).

  • Tman81 on 19/05/2025 - 13:37

    My impression is the Tesla is at fault.

    The Tesla needed to indicate prior to exiting to get to the outside lane and do so safely to exit, otherwise (I think) the inner lane can only be good for a slingshot lane (u turn) though I dont know that roundabout well so those that know the roundabout have better idea on how it works.

    The real key factor is those coming in to the roundabout on the first left. If you were coming in that way, is the left lane left exit only or not.

    ADDIT
    If youre coming in from the first left, you can go straight or turn right on the outer lane

    • Drakesy on 21/05/2025 - 15:41

      I have to agree with you.

  • GordonD on 19/05/2025 - 14:22
    +7

    A suggestion to OP.

    Between the text, and the MS Paint diagram, and the responses we were offered 5 different ways of identify these two vehicles. A and B. Blue and orange. Tesla and Mustang. Left lane and right lane. Inside lane and outside lane.

    If you are going to do an MS Painting, which is required, when you describe what happened in words, don't use another different naming scheme for which is which, and leave us to have to translate between your two different naming schemes, just refer to them by what's in the diagram. Blue and Orange. Or whatever.

    And for those using the inside lane and outside lane terminology, please get it right. The "inside" LANE is always the one CLOSEST TO THE CURB. Always is, always will be.

    • tenpercent on 19/05/2025 - 15:48

      CLOSEST TO THE CURB

      Which curb?

      Inside lane would be the one closer to the centre of the roundabout, outside lane would be the one further out from the centre of the roundabout.

      • GordonD on 19/05/2025 - 17:42
        -1

        Which curb?

        That explains why you don't know which is the inside and which is the outside lane.

        Because you don't know where the curb is.

        In Australia the curb is ON THE LEFT. What is on drivers right in roundabouts like the one in this case isn't the curb, it is a traffic island. In Australia lanes are always counted out sequentially from the left, starting with the inside lane.

        You are confusing two different things. The inside LANE of a road is the one closest to the kerb. The inside of a CORNER is on the left side of the road on a left hand curve and the right hand side of the road on a right hand curve.

        (My natural inclination is to spell the word as "kerb", but the NBN has seemed to standardise it as "curb".)

        • Maichu on 20/05/2025 - 18:35
          +1

          Except in a roundabout, the central island can also have a kerb. As an example, it is referenced by Vicroads:

          "To enhance the prominence of the roundabout, the kerbs on both the splitter island and central island should be light coloured or painted white."

          I must admit I was also confused by your post, but agree to have just the one naming scheme for simplicity

        • Nebargains on 21/05/2025 - 06:06
          +3

          You have lost your marbles if you think anyone would ever suggest the inside lane on a roundabout is the one on the left in this case.

          A roundabout is a circle with a small island in the middle, logically the inside lane is the one closest to the middle. I can't believe it his is even a point of contention.

  • Payne on 19/05/2025 - 15:41
    +6

    Initially I definitely thought Car B was at fault, but looking at the line markings on the road made me think…

    Is Car A allowed to cross a solid white line to go straight? It seems like they're being directed around the roundabout, and only the left lane can go straight.

    If we continue to follow the roundabout, we can see the next exit has no line markings on either lane so they can both continue straight.

    It's a confusing as anything, so no wonder there are accidents. They should add arrows near the exits to make it clearer.

    • Spuds Mchaggis on 20/05/2025 - 16:32

      Another 100% correct answer.

    • furyou on 20/05/2025 - 23:59
      +3

      yeh I clicked too early. Driver A (Right lane Tesla driver) is at fault.

      With dashcam, you don't cross a solid white line WITHOUT LOOKING at the car slightly in front and to the left of you the last 10 seconds.
      How hard is it to be aware of your surroundings, regardless who is right or wrong? You could be right and still dead.

  • AndyC1 on 19/05/2025 - 19:29

    THE most dangerous roundabout in Sydney strikes again. Never ever be in the inner lane and try to exit into Underwood road. Even if you are legally good as I have seen so many accidents at this exit.

    If you are in OZ Ave get in the left lane and go around the outside lane it is the safes lane to be in.

    In the afternoon there are more accidents than in the morning, but saying that the chance of seeing an accident is about 5 to 10% of the time I have used this round about and the near misses is about 10 to 15%.

    • ronnknee on 19/05/2025 - 19:50

      Is there really a safe lane? The car in the outside lane collided into OP.

      • AndyC1 on 20/05/2025 - 19:55

        Not at this round about based on my 10 years of working in Olympic park on an OZ ave corner.

        My only advice is go slow and assume the other driver will exit and will not look.

        The only time it is safe is when the lights are working, which is when a pedestrian is crossing. When a pedestrian crosses the road the danger is now that the pedestrian can be hit by cards not knowing what the light are for a pedestrian crossing the road.

  • BewareOfThe Dog on 19/05/2025 - 21:34

    Depending on line markings, blue is at fault.

      Its scary, isn't it. No wonder there's so many collisions at that roundabout and other multi-lane ones.

      poll

      licence

      Roundabouts were a good safety idea for low traffic volume intersections where the costs in dollars and vehicles having to stop and wait 'til they got a green of traffic lights weren't justified. They meant that when the inevitable collisions occurred they were mostly minor mudguard to mudguard ones that involved insurance companies, not serious front into side ones that involved ambulances. Then some idiot thought, hey, this is working, we'll scale up the idea to high traffic volume intersections by having multi-lane roundabouts. They've been a disaster.

  • OzzyOzbourne on 20/05/2025 - 09:24

    Looks like they updated the roundabout entry arrows to allow the left lane to turn right but didn't update any of the roundabout markings showing both lanes exiting, hence the ensuing chaos and calamity

    • cnut on 21/05/2025 - 22:19

      This roundabout is really messed up. I’ve watched the footage, read all the posts and the conclusion I came to is that the roundabout is broken and is missing clear markings at that exit.

      Given the Mustang didn’t have anything to indicate they can’t continue down that lane, but neither did the Tesla to say they can’t or shouldn’t go straight, this is a recipe for disaster.

  • endotherm on 20/05/2025 - 09:33
    +4

    If you are on the inside lane and you want to exit, you need to change lanes safely before you get to the exit. Otherwise you are making a turn from the right lane across another lane of traffic. Don't think of it as a roundabout. If it was a straight piece of road, how would you react?

    Not only that, the other car in the video looks like it was slightly ahead of you. What were you thinking? That the car would magically stop or disappear because you wanted to turn across his lane?

    • GordonD on 20/05/2025 - 09:49

      inside lane

      outside lane, the one furthest from the curb on the left, the one closest to the centre of the roundabout

      I realise that seems an odd use of the English language, but the alternative is even worse. You would have someone driving down a multilane road in what everyone agrees is the inside lane, the one on the left closest to the curb or hard shoulder, entering a multi-lane roundabout from that inside lane without changing lanes, and immediately being considered to be in the "outside lane". Its the same lane.

        • GordonD on 20/05/2025 - 10:46

          The inside lane remains the inside lane, the one closest to the curb or hard shoulder, even on a right hand curve in the road, and a roundabout is just a 360 degree right hand curve.

          • Muppet Detector on 20/05/2025 - 17:49

            @GordonD: Think of it like calling a horse race.

            The horse running next to the rails is said to be on the inside lane (on horse's left), and the horse running closest to the grandstands is said to be coming up on the outside lane.

      • Nebargains on 21/05/2025 - 06:09

        I would say 99/100 people would call the lane closest to the middle of the roundabout the inside lane.

  • OzzyOzbourne on 20/05/2025 - 10:48

    The roundabout is badly marked. If you choose the right lane to turn right and are then expected to change to the left lane somewhere on the roundabout before you exit then that's crazy because yeah, try doing that part way around and it makes the update of 2 right turn lanes at the entrance (originally just the right lane) to allow better flow to the right turn completely redundant and much worse wrt accidents. It's also not how roundabouts normally work. Ie. 2 right turn lanes at the entry and exit usually means just stay in your lane, but because they haven't updated the lanes markings on the roundabout then it's chaos.
    In fact, even with just the right lane for right turns it still meant crossing or changing lanes to exit. But has been made worse by the left lane also being used.

    https://i.imgur.com/1wzZjrG.jpeg
    The lanes should be marked similar to this, but this has the opposite problem with people who cannot stay in their clearly marked and signed lanes weaving in and out other lanes unnecessarily.

    • trapper on 20/05/2025 - 11:18

      The roundabout is badly marked.

      Agreed.

      Also note in the image you posted the outside lane is exit only at all the exits apart from the top one where the outside lane has the option to also continue around.

    • GordonD on 20/05/2025 - 11:26
      +1

      The lanes should be marked similar to this,

      Almost, but not quite. That one still has different lane line markings for different exits. Which you only see after you've gotten to them and its too late if you're in the wrong place, so you need to not just be familiar with the rules for roundabouts generally, but also how that particular one works.

      There are other ways it could be done, but unfortunately every way creates its own different problems. Multi-lane roundabouts are unfortunately fundamentally flawed because you always have some people trying to move to the lane to the right of them to stay in the roundabout, at the same time other people are trying to move to the lane to the left of them to leave at the next exit. They block each other. The whole idea only works at all when there's one lane. Or its not busy. And the point of multi-lane roundabouts is to handle high traffic volumes.

  • GordonD on 20/05/2025 - 11:14

    We regularly have who is in the right/wrong after a car crash threads here.

    They almost always result in two completely different opinions.

    In this case we can't even agree on the nomenclature of which is the inside lane and which is the outside lane on a road.

    So last time we had one of these threads I reached out to my state's police commissioner's office and asked if there is someone who could be tapped on the shoulder who'd be willing to log in when asked, and give us an official authoritative police view of the relevant road rules. I haven't gotten a response as yet.

      A cop doesn't know all the laws, or even all the road rules either.

      Especially in usual cases. He will need to go off and look up the relevant laws to figure out what exactly applies and who gets fined (or charged) for what. Even then the court may disagree.

  • Powershopz on 20/05/2025 - 11:19

    That roundabout is really poorly designed. Can see in some of the prior comments it used to be that the left hand lane could only go straight.

    Considering the internal lane can only turn right on 3/4 of the entry points the road lines should really be repainted so that all exit similar to the west to east route.

        You failed to include the line directly below it: "You must give way to all vehicles already on the roundabout."
        Therefore, the car in the right lane turning right IS ALREADY IN THE ROUNDABOUT. So the car in the other lane also turning right (that magically decides to do a u turn instead of turning right) MUST GIVE WAY TO THAT CAR !!

              @lainey13: So is the Mustang not on the round about? what did the Tesla hit? do you even see the road markings? the markings SHOWED that the Mustang could continue doing his U turn or turn off. If the Tesla wanted to exit then like a normal road he is required to indicate and merge safely which he didnt and caused an accident

              The only time the Mustang would have been in the wrong if the round about had road markings like the link below, refer to the cars in the top right. Imagine the Mustang as the black car, the line here indicates he must turn off. Now imagine the Tesla is the white car next to the black, here the white car car exit as well with the black car or continue to the U turn. The OP scenario is not like this at all. In OP scenario imagine the white car is now the Mustang and the other white car closest to the roundabout is the Tesla. In this scenario the Mustang can exit or continue to U turn. The Tesla must continue to U turn and can exit the next exit or continue U turn. Not sure why you guys think there is only 1 exit in this round about.

      Totally agree with Lainey. Driver A shouldn't get penalised for the messed up road markings - overriding basic principles of using a roundabout apply, don't do a u-turn from the left hand lane!

        OP should not assume that the Driver B will exit the roundabout. What if hypothetically, there's a Driver C entering from the left side of the OP (Australia Avenue) on the left lane where where he is allowed to turn right (yes I checked google map, unless this has been updated) - he would end up in the same lane as Driver B and is allowed to keep going to turn right (essentially Driver B U-Turn from the left lane).

        If OP looked left and give way to any traffic before crossing lanes, this accident would never happen.

        • Browsers on 21/05/2025 - 14:40

          That's a fair question. Driver C entering the roundabout should/would have to give way to any vehicles already on the roundabout, and so would not be alongside Driver A at the exit with risk of collision. The staggered entry of vehicles is what keeps the flow both constant and safe for most roundabouts. Consider also if both vehicles A and B had entered from Australia Ave to turn right onto Homebush Bay Dr. The exit markings shown on Streetview are very different from the exit where the incident happened, with a break in the line that clearly provides for both lanes to exit. The same is true of the other exit onto Australia Ave. This just highlights the fact that when the entry marking arrow was changed to permit Driver B to turn right from the left lane, the lane markings within the roundabout should also have been adjusted. The flawed markings contribute to the accident, but they don't absolve driver B for the douche move of attempting a u-turn from the left lane.

    Hoping these accidents will be the thing of the past after these planned upgrades.

        I think that's just a interim solution.

        Eventually they'll upgrade to this:

        A signalised intersection, configured as a Diverging Diamond Interchange performed best overall when compared with the other options, and was selected as the preferred option

    I’ve been watching a load of dash cam owners aust videos and I swear every week there is one of double lane round about incidents. Usually like the way OP crash. Where the inside lane wants to exit and the outside lane wants to continue around. Sometimes the outside car entered with OP, sometimes they have entered on the left, no matter when they enter the car in the outside usually thinks they have the right to turn, I mean the arrows even says so in the ground sometimes.

    But it’s obvious the inside car needs to exit at some point and that means crossing across the outter lane.

    So with all this in mind it’s easy to see the natural conflict and drivers just need to realise this and watch out.

    OP needs to left indicate to signal leaving the exit, and watch blind spot for cars, mustang needs to be aware the car in front can be exiting and watch for angle change and hopefully an indicator as well.

    Some of the comments help to explain the number of crashes on our roads. If the mustang wanted to do a u-turn, they HAD to be in the right lane.

  • Euphemistic on 20/05/2025 - 16:27

    Doesnt look like a double roundabout to me. Its a 2 lane roundabout, but theres only one circle isnt there?

    Since the Tesla driver is on the inside lane / right side he cant just cross over into the left side as theres a line indicating that Mustang (car far left/outside lane), refer to first link above, can keep turning on the round about or exit. If that is incorrect the road sign on the ground at the start of the video and the lines on the round about really needs to change as they are confusing as for drivers.

    Shared from another user. Here you can how lines should be if the Mustang could not cross and must turn out if you think about the top part of the round about and the outer 2 lanes.

      Yes you are 100% correct the Mustang driver had all rights to continue and exit where he likes. The Tesla must give way prior to exiting / changing lane.

      Looks like you're right, but that's pretty confusing!

      I grew up driving with only normal roundabouts, where left lane can only go left/straight. Seen a few roundabouts like this with weird rules only in recent years and it's an absolute trip.

      Trying to do a U-turn from the left lane is chaos, and I'm surprised ANY cars make it through this roundabout unscathed. Seems like guaranteed confusion and faulty design by the council.

    Regardless of what the lane markings are, doesn't it make sense not to drive in front of other cars?

  • ramb9 on 20/05/2025 - 18:15

    Agree Mustang is in correct. The lane markings open up to allow Mustang to keep driving in the roundabout.

    Tesla shouldve merged safely to exit. Also if driving with eyes, he shudda saw the guy and stopped since the mustang is in front.

    Either driving with autopilot or just god awful driving.

    Given Tesla needs to give way to cars already in the roundabout and Mustang is in front. Tesla is at fault 100% no doubt

    Tesla 100% at fault for crossing marked lines into traffic of the other lane.
    If the line markings directed traffic out towards exit then Tesla would be fine, but line markings shows that you need to change lanes to exit.

    Mustang is in the wrong, but Tesla could have prevented this event from occuring by braking to avoid the collision.

    • kiwimex on 20/05/2025 - 19:56

      Please explain how on earth the Mustang could be in the wrong? The Mustang hasn't changed his lane and has all rights to maintain his path through the round about.

      • ParkingFine23 on 21/05/2025 - 18:33

        That is incorrect. Each entry lane to the round-about has painted markings which show which exits may be used. According to the markings on the road, the Mustang must exit on or before the right exit, relative to his entry point. So must the Tesla. If I were to extend your logic, the Mustang is entitled to sit in the outside lane of the round-about indefintely, and just do loops in the outside lane for hours, and everyone in the inside lane has to put up with it and cannot exit anywhere, because the Mustang is in the outside lane, which must be traversed by any vehicle in the inside lane to exit the round-about.

    Really poorly designed and marked roundabout, but in the end the Tesla driver failed to follow the golden rule for any lane change:- give way to any vehicle already travelling in the lane you are changing into.

    Irrespective of what happened upon entering the intersection the Mustang driver stayed in their lane and the Tesla driver changed lanes, so in the absence of any explicit signage or road markings indicating that the left lane must turn left (and stay in the left lane) at the Underwood Rd exit the Tesla driver was at fault because they failed to follow the golden rule.

      I voted for driver B but now I'm convinced that it's driver A with this argument.

  • ozgeek on 20/05/2025 - 22:19

    Tesla is in the wrong. You can't exit the roundabout from the inside lane only the outside lane unless there are road marking that you can.

    Im truly astounded by the poll results. Ultimately they could argue both were at fault with varying % to blame however the Tesla is definitely the one that caused the accident and more at fault.

    OP. You're taking a video from YOUR PHONE.
    Why did we have to watch half a minute of useless crap for the 3s of the actual crash (which isn't caught)?

    OK you don't know how to DL a Tesla dash video, but you can't start/stop YOUR PHONE to waste less people's time?

    I think both parties with fault both are in wrong lanes.

  • c9 on 21/05/2025 - 00:57

    I am genuinely concerned if some people don't get this correct.

    Left lane has rights to 3 exits only, left, straight or right. There is no 4th option for this car to stay in the roundabout because car on right lane needs to turn right and rightfully need to exit a roundabout.

    There are places that roundabout can have 3 lanes. Middle lane can only go straight using 2nd exit. Not a chance for the car in left lane to stay in roundabout and make an U turn (using 4th or 5th exit), it is just asking for accident to happen if that's legit.

      Im genuinely concerned that youre genuinely concerned that you think you're correct here.

      Just watch the video and pay attention to the lane markings at the exit just before the Tesla hits the other driver (who is in front of them also).

      Its legit what you think it isnt.

      On that note, first time I've seen ozbargain so ridiculously wrong on a accident poll result. Hope OP updates us on the insurance claim.
