They also seem less likely to be comfortable riding on the road (understandably) so illegally use sidewalks to a greater degree.
Of course, we've still got the rental e-scooters, so our supply of "people riding way faster than logic, wisdom, their wheels, and the surroundings would suggest" is still adequately supplied.
I think there’s some expectation for bikes to go with traffic, rental scooter riders think they’re some kind of unicorn where right of way no longer applies.
And I am assuming they are rental scooters because of the styling and lack of helmet.
I am hoping that as time goes on these newfound e-bike owners will get more comfortable and will respect traditional biking norms.
Another phenomena I've noticed is a lot more kids with e-bikes, oftentimes 3 kids to a single bike.
