Gyrocoptors have been, and still continue to be a thing, for like... 85 years. The design has not been ever marketed as a "flying car" (to my knowledge), though it does have a relatively short takeoff roll compared to conventional aircraft. Search for "autogyro".

I hope people give up on this 1950's-era mythological obsession with trying to realize a cartoon's flying saucer pods because of the potential for energy waste/climate change, public hazards and property damage.
