I must missread something somewhere. I put much more weight on the terror side than the accident side.

If i was a civic engineer and a law maker and i would need to start making infra for flying cars, cities would be no fly zones, outside of dedicate “roads” that can be designed in so there is minimal danger to others in the case of crash. There would need to be dedicated flight height. These could be enforced similiarry than rentable electricscooters are now, so if driver would drive on a no fly zone or at wrong height the car would slow down. These would need to be build in things from the manufactorer. These no flight zones would also be near anything dangerous like energy plants, airports, military instalations etc etc.

We have allready things like automatic braking because pedestrians or deer or other cars. These would need to be supercharged so the vehicles do not let people drive to close other people or buildings.

Then things like harhers punishments for breaking the traffic law, more strict inspections for the vechicles and own permint for driving flying cars, that is prerequisite to buy a car and if you loose it, you cant keep the car, or there needs to be a mechanism where the car is made earhbound only.

Clear idea that flying is not a right, it is a responsibility.
