There's a strict rule on the Mass Transit board that guys like me are not supposed to "admonish users for their choice of mode of transport". But I feel the need to point out the difference between levitation and flying.
I've worked numerous projects that proposed different types of levitating AGT and non-automated Maglev vehicles, and they levitate less than 1/2 inch off of a flat surface plane. What Bandit957 is referring falls in the category of flying cars (which have been around since before the Wright Brothers). Today, there is also the newer technology of Personal Air Vehicle (PAV), which is more like an autonomous passenger air drone that is capable of autonomous driving on surface roads. Both of these technologies are literally "waiting in the wings" of the autonomous vehicle craze because most folks are not willing to take the cost risk of a product with an inherently high safety risk (ergo, risk = frequency x severity and the most frequent severity of air crashes is catastrophic). All that being said, I find all of these levitating and flying technologies to be very interesting.
Another category outside of the ones that Bandit957 is talking about is the Air Taxi philosophy. These are small, personal sized traditional aircraft intended to be bounced around between small airports similar to ground taxi fleets. Each one needs a certified pilot and would have the advantage of fleet ownership. Canada has a small, but healthy Air Taxi industry but it has failed to get jump-started here in the States. But I point this out because the advent of small VTOL (vertical takeoff and landing) and eVTOL (electric) aircraft has the potential of making the Air Taxi industry much closer to what Bandit957 is suggesting.
There's a bunch of technical issues to get past approval from safety guys like me. Much of my world has just switched over from Department of Defense system safety protocols to Aerospace Industry system safety management processes. I've yet to get a handle on all of this (both in the mass transit world and in flying car world), but it looks like a really tough nut to crack open.
Hopefully, this sets the tone for the next round of comments.
