I don't think you got the memo where everyone seems to think getting blind drunk and then getting on an electric scooter is totally ok "in Sweden".
I've had a few near-misses myself with crazy drunk riders on pedestrian streets in central Stockholm; I once interviewed a job-candidate with a cut-up face who laughingly told us he'd crashed a scooter with two(!) friends on the back after a drink night; a friend of mine smashed their hip after a night drinking and then jumping on a scooter.
The rules may be there. The actual reality is different.
But the "folk wisdom" of drivers completely ignores that threshold and only considers the next stage relevant (BAC 0.5+, used to be 0.8) and this only applies to motor vehicles. For cyclists, the next threshold does not happen before BAC 1.6. I suppose that wouldn't exactly be allowed in the UK either?
