Yeah it's ridiculous.
Boomers legislating away a method of transportation they have no use for, combined with a few people using it with little regard or civility, and rental operators so focused on competition that they're unwilling to enforce the rules.
But really, mostly it's the first of the three factors. Thank god they're avid adoptors of ebikes, making those safe for now.
In several countries in the eu (if not all) they restricted ebikes to 25kmh.
Car driverss going at 30kph get really pissed off.
I'd love an ebike for work travel but dislike playing tag with 1-tonne machines. At least on my road bike I can ride at a casual pace, with occasional mad accelerations.
It seems less dangerous to me to go at 15kmh.
