FWIW I was just in london and saw a bunch of people riding their own Mi scooters in the street. (That's the same scooter Bird uses.)

I'm seeing more and more on my commute, but it's the difference between a few people buying their own from Alibaba and a company installing them across the city. The former's unlikely to draw attention from the police, the latter much more so.

Sure, and people smoke week or break the speed limit despite the legality.

Err, why is it illegal? They're more than fast enough to keep up with bike traffic in the city, especially if there are dedicated lanes.

Basically, the laws say that your vehicle must be licensed to be used on a road unless it’s a bicycle/pedal assist bike/a few other categories, and there’s no mechanism for licensing some of the newer transport options. The laws also say that a vehicle can’t be used on the pavement at all, so there’s no way they can be used on a public road at all.

And have you ever seen a picture of most British cities - there’s barely enough room for cars and pedestrians sometimes, never mind a whole separate lane for cyclists/etc.
