Interesting.  I commute by bike in SF and see electric skateboards on the street pretty frequently– I&#x27;d assumed they were legal.<p>Anecdotally, their speed seems like a good fit for the bike lane.  I keep a pretty good pace on a bike, but still find electric skateboards occasionally passing me (especially if we&#x27;re both stopped at a light, since their acceleration is a bit better than mine).
