When flying vehicles become feasible, there's no way the public should get access. Instead, it should be for trained emergency services (Ambulances, fire trucks, police) to ensure the fastest/most efficient possible response time. We already crash too much, no need to add flying.

EDIT: I should clarify: I'm talking about decades from now, when tech had evolved to the point where is if perfectly doable an feasible for flying cars to be just as common as regular cars are today. Not helicopters, they are expensive and rare (when compared to cars). What's the police car/helicopter ratio for an average station? I'm talking about when we've reached the point where you won't need helicopters at all, because the the cars will be flying anyway.
