>>I’ve seen some of the three wheeled motorcycles (if you want to term it that, and this may not be what you are referencing), and they are quite appealing.
Google the Elio. It’s a 3 wheel tandem-seat enclosed vehicle with an A/C.
If I had to buy a hybrid, it would be a Prius. I’ve driven one and they aren’t bad for a tiny car. But, again, if it came to that (i.e. $8/gal gas), I’d go with something small and cheap that costs under $20k and gets 40 mpg (the small Kia, for example). But, even at $4/gal, its just not worth the trouble.
About seven to ten years ago, I saw something like that out here in SoCal in a few independent auto dealer show-rooms.
The ones I saw were rather flimsy. These may be put together more sturdy.
The problem for me is that I need something that I can take on the freeway, and I don’t think I’d really feel good in that Elio in that situation.
