well, i think pretty much every one of the points that you covered can be done just as well or better on a bike, but it does have some good things about it. i think it would be ideal for city and town travel...now if we can convince ford and gm and chev to start selling these, or get entire cities to sponsor something like like so everyone in town has one, it would work. it is a little pricey though. it would work very for some people though. now if everyone had one, it would be perfect. haha its kind of like the flintstones lol.
