If the plane handles in the air like a Cessna, it will be a barfmobile.
At least for the passengers. The air is a pretty bumpy ride for a small aircraft, even at good weather. The effect is much weaker when you are at the controls, though. Don’t ask me why. Piloting is nice but being a backseat passenger for longer than very short rides sucks.
Edit: My idea of a flying car is a twin-rotor ducted-fan hovercraft. Lightweight, with liftable skirt and wheels for common driving and fuel economy, but with ability to hover over bad or nonexistent roads or over water, and to fly over shorter distances. Then you can have the best of all worlds - good smooth rides over empty roads, shortcuts over meadows and water bodies (bridges are common choke points of urban traffic), and aerial transit between the road and the shortcuts, and over traffic jams (the poor fuel economy for short-range higher-altitude (low dozens feet top) doesn’t play much role for just few seconds of actual flight).
