Like all "flying cars", not a car, and not a plane, either. Maybe the guys who are obsessed with "building a car" that can "also fly" and "also swim" (that one failed badly, too) should consider to "build a train that people can use", or "build a house that people can afford". Instead what they do is "oh wait, highways are nasty, let's build a future where that nastyness is IN THE FREAKING SKIES ALL AROUND YOU". FU.
