Yeah, theres a handful of reasons I doubt flying family cars like that would ever be a thing

1. I know I wouldn't get on a plane without a pilot, and I doubt many other people would too

2. I would not trust the common driver with a vehicle capable of 3 dimensional travel. Traffic laws would be insane, drivers going above or below the flow of traffic and likely causing accidents sounds like a nightmare

3. Anything fails and your ass is done. You run out of gas on the road and it's an inconvenience, in the air its death. Same thing for complete engine failure or something as simple as a air filter issue shutting off the engine. While these could potentially be sorted out, please tell me how safe bailing out of a flying car, potentially with children, would be in an active air traffic scenario of mass acceptance of flying cars.
