Haven't seen too many of these things around. This bloke was unloading his from a neat little carry thing on the back of his car as I drove past. His movements were a bit jerky, so I suspect he might have had some sort of motor-neuron thingy, which would explain the use of a Segway around town.
It barely took him any time at all to unload the Segway, mount up and shoot through. I barely had time to do a U-turn, pull out the camera and grab a snap before he was off.
I still remember the hype that was generated before these things were released. And look at them now - how many are around? Stuff all. They never took the world by storm as expected.
