A Strange Car Blocked My Driveway, What Should I Do?

Hi guys, I’m looking for an advice where a strange car was blocking in the middle of my driveway and the next door’s drive way. I took some photos but don't know how to attach them here. I also noted the plate number just in case it will repeat. The strange thing is there were many empty spaces that the car could use.

It happened before when my next door came and asked if the car that blocking his driveway was belong to me. But this time a strange car is blocking both of our driveway. I’m not sure if it is the same car that blocked my neighbor’s driveway.

Luckily, this morning I parked my car outside and I was rush to work, so I didn’t bother to find out who parked the car there. My question is what should I do if that car blocking my driveway again?

Thank you in advance.
