> drunk partiers using them

at least in England, if you use an e-scooter while under the influence of alcohol, that equates to a motoring offence whereby incurring (car) driving licence penalties, driving licence disquaifications (bans), fines, and imprisonment all apply, depending on circumstances and severity. I'm not sure if/why it would be different anywhere else

Yeah I do not think there are any serious transit advocates that put time into advocating for e-scooters. They are worse and more dangerous than bikes and e-bikes in every possible way.

And any bike lane infrastructure would benefit e-scooters anyway, so riding them in the road at 30mph below the flow of traffic is a sad hill to die on.
