This electric stuff is all going to end in (more) tears.
On my route I have electric scooters in the road, cycle lane and on the pavement. Some fast, some slow ( in the cycle lane and getting in the way). There are unrestricted ebikes that are incredibly fast and quick off the mark at lights. They are generally in the cycle lane but are too fast and don't have the manoeuvrability of a push bike.
Sadly government and regulation don't move as fast as technology.
I think there's a general view that under 15mph and in a bike lane you are OK, people on here obviously know the law and that isn't the case.
Having said that you have lots of idiots on bikes.
PS. I'll leave the skateboards, longboards and mopeds/motornbikes in the cycle lane to another day. It's a jungle out there peeps.
