in my post below. If the commercial model had enough power to handle hills, I would've loved to have rented a couple of them in San Francisco last summer. Riding one of those around town would've been a lot more fun than driving and looking for parking spaces for our minivan. It would've been fun to see how fast I could go down "Crooked Street", too. I got there early one morning and averaged over 20 MPH in my wife's minivan. An IT would be even more fun.

If they became available as rental vehicles, I'll bet they'd be popular for family vacations. Your GPS idea is good, too, especially tied to advertising local businesses. Sounds like the start of a good business idea if the liability issues can be resolved.
