They're illegal
@postman but the police in Leeds don't seem to do anything about them. Nor near me. West Yorkshire police's attitude seems to be to clear up any mess, rather than deal with the crime.
They're the latest drug dealers transport of choice; silent,
can do 70mph and get through gaps easily.
Same here, all the low level drug dealers have cottoned on a year ago or more that they're untouchable on a scooter.
The Police either aren't interested, or don't know what to do about them, either way there's total inaction.
I handed over footage of a local drug dealer recklessly carving through traffic at 40mph, gave them his regular route, where he does his deals, they just said "thanks". And 9 months on, he's still doing exactly the same thing, same places, every day.
This is why people don't bother reporting things.
