It'd be better if cars had some sort of built-in warning system that could be activated when a driver sees another driver doing something dangerous.
Flashing lights would only work if the drivers causing danger or the drivers in danger were behind the car with the lights, so the warning system would probably need to be some kind of a loud sound, easily recognizable as a kind of "hey, watch out, something dangerous is happening" sound.
