Very cool concept.

Yes, that is cool. There are other "leaning" vehicles, but they are 3-wheeled in which only one wheel leans.

He has this 3 wheeler on one of his web pages.

Here's some section views of the new vehicle.

Unfortunately, because it has 4 wheels it will be treated as a car, but if it had 3 wheels it would still be a considered a motorcycle, with much simpler regulations. I really like the 4 wheel, enclosed design.

I think the government, the car and motorcycle companies need to get proactive and lobby for a new set of regulations for a light weight personal transport vehicle like this one.

The aviation industry did just this, with the new sport class aircraft and licensing.

We need a new set of laws for light weight vehicles, that have requirements closer to the motorcycle regulations.

Come on GM get moving on this, too.
Hire this guy!
