For what it’s worth the UK uses mph and we’ve had the Internet for a little while now too, and here e-scooters are technically illegal to ride anywhere other than on private land, i.e. not on pavement, on bike lanes or on the road.

The exception is if you’re in one of the cities which is operating a “trial” rental scheme, in which case the rental company will let you know where they think you should ride. But I believe even in those areas privately owned e-scooters remain illegal to use in public.
