Perhaps it's my inability to think with the 'correct' side of my brain (or more likely, the limited size of that brain!), but without some fairly high-powered graphics computers, I don't understand how the image will present an "aerial" view of the surroundings. A 'panorama'
would be fairly simple/easy. When I started reading I kept waiting to hear about a multi-lensed "camera-on-a-stick" popping up from the car's roof to capture the "aerial" 'image!'
I could just imaging that thing getting stuck up there and hearing a 'strange' sound upon leaving one of those extremely low-ceiling parking garages!
