  • Wouldn't waze be better than speed camera? It gets live updates of road hazards (including police and speed traps) from other waze users and gives directions at the same time.

    • For traffic hazards etc. yes. But for cameras etc. I doubt police is willing to give up their locations.
      Plus Wave has ads but I agree it is a great app.
