This. There's an element of snobbery often in this discussion where there's a disdain for people who haven't "worked for" the movement they're getting.

Which seems besides the point. The reason you can't ride a motorcycle in the bike lane isn't because you haven't worked hard enough to deserve it, it's because of the top speeds and mass of the vehicles presenting a danger to others in the lane. It's the same reason cars present such a danger to cyclists - the scale of kinetic energy going around is just too high.

I think fast e-bikes are a technologically interesting thing, but from a regulatory point of view I'm much more mixed. ~30 kph seems eminently reasonable for bike infrastructure, and I'm excited about the ability for that to displace car trips - both from a sustainability perspective and a road capacity perspective. Much faster than that though?
