well this does not go against my initial post with one exception
make backup alarms mandatory on all cars along with some flashing LEDs
to show which car is backing up.
teach drivers going out of parking place head first(not int reverse) to honk the horn before pulling away just in case their view is obstructed, and be cerefull any way when driving away.
this is the only situations I do agree that are dangerouse and put cars and pedestrians on equal ground.
