MUahahahaha, but true: a convenience for the affluent. Not that that won't make Kamen rich, and deservedly so. But it will sure get the anti car Nazis' knickers in a bunch. Just wait till Land Rover comes up with a retrofit that replaces their neat hydraulic bumper-step with a thingy that will lift your Segway into the back of your Discovery.
Agreed; this thing is destined for page 12 of the Sharper Image catalog, next to the robot dogs.
To put this into context, for $8000 I can buy two Boattail Buick Rivieras, and a full-length pimp ermine coat; and when I drive it on the sidewalk, I won't have to worry about people will getting in my way.
