You guys are thinking way too high tech. My son recommends a skateboard.

Those things are dangerous, and lots of work. Those little
skateboard/scooters (with handle bars) are better -- and better than
walking -- but they're still too much like work, too.

We always see the annoying gas-powered versions of those things at OSH.
I've never yet seen anyone kill themselves on them, yet, but I always watch
anyway...
