Weren't these things supposed to change the world?

It's a very odd thing to be on a Bangkok street and see a group of tourists on Segways glide past. They seem like a good idea for those who are unable or unwilling to walk very far, since seeing very much of what Bangkok has to offer requires a lot of tromping around. I doubt that there will be many Thais doing this, though, as the price - about $85 for a 2-hour tour - is prohibitive for most locals.
