> I saw just a couple nights ago some kid doing what appeared to be about 40mph on an eBike. Wind in his hair, not pedaling, just blasting it.

Saw an ebike zip past me at about 40 MPH in a wheelie, little motor screaming, splitting a lane in traffic. (El Camino Real, Silicon Valley). If anything happens ahead of them, they're toast. Can't stop and can't evade.
