Smaller aircraft powered by more modern tech and engineering? Sure, I don't doubt that. But when you compare it to a car, you imply something that the average person might buy (or be able to afford) and I just don't see that happening soon. Even hobbyist quadcopters and "drones" are throwing the FAA for a loop so I can't imagine more than the private-jet-set buying a smaller, personal aircraft and paying to license and fuel the thing just to make a run to the grocery store or commute to work. Smaller, "smarter" aircraft aren't the same thing as flying cars in the way most people will interpret the term.
