Keep one in the back of your Lincoln Navigator. It'll come in handy when you can't find a parking place close to the mall entrance.

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.

Now, that would be an invention! Something compact you can ride and store bags of junk on, that will easily fit in a normal sized car! Another good idea was putting the horn thingy with your keys. I have a tendency to lose my car a lot and following the sound of my horn saves a lot of time. I use it all the time.
