yes i know it was unveiled in 2009. i was there when it was unveiled. but the thing is, it is still in developement, because of it's complexity. when i was at the unveiling, they showed an animation that depicted special sidewalks/roads that were adjacent to the streets that would be made specifically for the PUMA. also, compared to the segway and other similar vehicles, this is quite fast: top speed of 35 mph. plus you can have 2 passengers
