In contrast, bike paths have for the most part been power-limited, with those able to sustain unreasonable speeds hopefully having the experience and judgement not to do so.

Right now, the culture just isn't there for e-things without appropriate firmware speed limits to be on MUPs.

What we probably should be doing is encouraging light electric motorcycles with all the road-safety requirements and registration, and also more compact electric cars, for use on everyday roadways. Unfortunately we've now got these light motorcycles without the safety features or registration, regularly operating in our bike lanes faster than the uncongested flow of the adjacent car lanes. And misguidedly, rather than try to make delivery a living wage occupation, this risky and intimidating behavior in the race to minimize costs was just legalized.

Motors on bicycles should be limited to bringing less capable folks (or those who don't want to get sweaty) back to what an ordinary person (ordinary, not a cycling athlete) could sustain over a half dozen miles or more.
