I personally don't need more, but I don't think I can say that no one does. My bike is already fast enough that I wear leathers when I'm gonna be taking it up to max speed, it'll do about 60km/h. It's technically not legal in my area, I didn't know that when I bought it, and no one seems to care about actually enforcing that, though I would imagine enforcement would like center around the selling more-so than the riding.

I think there isn't much reason why a motorbike is ok to be on the highway, but an e-bike capable of the same speed shouldn't be. But I do think e-bikes capable of that speed should need a motorbike class license to be driven on the road. And the same dress code should be expected. Dress for the slide, not the ride. I do also suspect the venn diagram of e-bike riders likely intersects more heavily with the safety conscious than does one for motorcyclists. So it should likely be less of a problem than the one that is already considered acceptable.
