Since we are talking about it, lets not forget about my e-167. It was a gen one segway that would balance if you were on it or not. It 'self parked' while on.

I loved it, and would still have it had it been a gen 2 unit. (I had both at one point, and the lean steer won out over the riderless balance feature.)

A standard segway, of the original design factor with a central upright or a lean steer, will stay in balance mode for a short while after you get off, but because of the handlebar shaft being mounted forward of center, it will lean forward and drive forward on its own.

However, it has a 10 foot 'leash' and will not glide farther than that with no rider sensors depressed, and shut down.

This way, if you step off the segway, it will not immediately shut down and fall on you. Instead, it will glide away a short distance, and fall on its own.

Of course, these are the old rules. The newer units will likely do other things, I am not familiar with...
