Yes, that's why I said "little practical use", rather than "no practical use".

I'm suspicious of your thesis that Segway price is the main problem. Electric bikes and Vespa scooters cost about the same, and I see far more of those around San Francisco than Segways. The only Segways I see outdoors in SF are people on a group Segway tour, which suggests that they are more valued for novelty than practical benefits.
