I understand your point of view, and I respect you for that. Motorized bike owners are a special rare breed. You need to be someone who enjoys tinkering with his hobby toy, which is what it is to many of us. In Hawaii, I've just seen one other MBer, and he was pedalling with engine off. People are in such a rush, but 99.9% will not think out of the box to find a solution to driving their thirsty SUV'S for trips about town.
Hawaii is the moped capital of America. They're everywhere at all times of night and day. I'd like to buy a moped because you can get a good deal on new and used ones, and they can be modified to go fast. Sadly, they get stolen a lot and quite a few get into accidents, sometimes fatal. Of course, mopeds are banned from sidewalks, bikepaths and bikelanes, which are my safe havens when I don't feel like mixing it up with overly stressed commuters.
Look Mom, no registration or insurance.
Go get your moped.
