I don't trust people driving cars on the highway, let alone flying around town.
While it looks gorgeous, this isn't a flying car. This is an easier to move aeroplane. You still need an airstrip to take off and land.
Rotary wing-based flying cars are a better bet. Kinda like what these guys do: http://www.krossblade.com/.
cool car, my biggest concern is the onepage layout who adds sections I've scrolled by to the browser history...
