It does seem like the safety benefits are there; there's really something to be said for getting pretty close to a motorcycle and still having something that crumples before you hit the ground. I have to agree with the enviro-wacko-crat comment though- the Prius actually sells because it's a real car that happens to be more environmentally friendly, whereas this fails on most counts to be a motorcycle while being friendly. I also agree with the sentiment about three wheels- my general experience with anything on three wheels is that you *think* it's considerably more stable than it actually is, so you try to have fun on it like it has two but just wind up scaring yourself silly.
