Why? Is it the Jetsons? Is it the exhaustion from the traffic jams during which we look up and see the empty space and somehow know for sure that we should be there rather than glued to the black pavement? Is it just a romantic attachment to the idea that flying represents progress?

Whatever, we can't shake the sense that it is coming. But it is more complicated than it first appears. Does this thing require a runway? If so, you have to drive your flying car to the airport, and you just know it is going to look a bit silly on the highway, and what's the point when you can just take an Uber to the airport and fly your private plane anyway?

You pretty much want this to take off from your driveway, but then you have a problem with neighbors, tall buildings, and telephone lines, not to mention government regulations. That's only the start of the issues.
