There would be one problem about these thing... hacking. Imagine if someone hacked into one and flew it into a building. But still I would want the second one and the fifth one I mean the first was is pretty much a plane sitting on a car. But they are so much money!!
that is really cool but looks like a lot of money to buy it for. and if their were flying cars they would be impossible to park unless their were designated landing spots everywhere which would take up a lot of space and make it hard to find a spot with so many of them.
(but this is really cool)
