I think the key part of ebikes though is just how versatile they are that makes them so much more practical for a lot more types of trips than anything you mentioned (although I don’t know what the aerodynamic electric vehicles you’re talking about are)

Ebikes make doing a lot of things you would otherwise need a car for easier. I can’t pick up my kids from school on a scooter or carry as many things on a regular unassisted bike (or at least it would be much harder). Ebikes might not be able to do everything but they can do a lot.

For a society that is so dependent on cars I think ebikes are a real game changer for that reason.
