wow, so much ignorance in here
first it isn't the first concept of a single/dual passenger personal mobility vehicle, toyota came out with a crazy 4 wheel version that reclines into a streamline high speed mode or stands tall for low speed general transport.
second those who think it'll be a reason for other countries to laugh at fat americans, it actually will have more appeal abroad than at home, highly congested urban centers in asia where mopeds are the norm would probably be the best target markets.
Now i don't think GM is making many smart moves at all as of late, and this concept is a bit strange, and probably will be executed better by asian manufactures, but a lot of what is being said in here is wrong, and just dumb.
