Other places too, and normally I would have only expected to see them in town. A few days ago on a back country road about 90 minutes out of town (where I would normally expect to only see somewhat serious riders) coming the other direction was an e-unicycle. A small wave of recognition in passing and I had to then give myself a shake and ask ... "did I really see that?" Clearly my expectations about where folks would ride an e-unicycle were very wrong.That exists in Japan at least:
Next up, I guess I shouldn't be surprised to see an e-scooter on the road in the middle of nowhere either (although I'm not sure it would be legal to do so).
The proliferation of technology (compact and efficient batteries and motors) means the potential for all sorts of vehicles on (and just off) the road. With the rapid pace of change driven by that technology I sure don't envy those drafting regulations and providing enforcement ... although I would love to see a LEO with an e-unicycle pulled over on the side of the road, it would make a great (and funny) picture.
