I guess pitman got me on that one. if you use too much gas just getting to work, your car isn't efficient enough. We do have a guy that rides a scooter to work(no he's not a drunk) and somebody said he gets 90+ mpg. I think it would be great as long as you didn't have to go a really long ways and the weather was reasonable, which here it probably is 80% of the time. They tease him about his "liqourcycle" but I think its smart.
