Electric scooters are illegal in the UK, but police don't have time or inclination to stop their widespread usage on public roads, and you're safe to ride past them unless you're doing something stupid.
So many things like this have people getting away with it that the laws are just ignored eventually.
When one has an incident ... Well, the hand wringers are out in droves telling everyone they told us so.
Underfunded and under resourced police can't cope with the workload, for a change.
