My comments above are about what i see in my area, i will add, and i think most of the e bikers i see are using them as intended. Nobody is putting in hot rod batttery packs that i know of (but ihave seen commuters doing this—. If i see someone going uphill at 12 mph on my way to work, then note that they are not pedalling, something is wrong there
And ive never seen any of the bikes that may be a scourge in other areas — the bikes that look like full downhill bikes and with motors where the crankset is supposed to be. I agree- those should definitely be restricted if possible. And the “extreme sporty sport” types on them blowing out berms would be better off on a real motorcycle
