In my experience it is the majority of users here in London. They feel like quasi pedestrians so they run lights, use pavements and operate without a driving license (as required by law). Given at the moment there are so few of them relatively speaking the coming epidemic of scooters will be a disaster for pedestrians

I'm not saying they get a pass, I'm saying that if you're also not outraged at the way cars are operated you've got a double standard. It's very trendy to hate on scooters.

That looks like a recipe for broken bones.

This is illegal in the UK. You cannot legally drive a privately owned scooter in public. They are classed as vehicles and you need to be insured to drive them, you cannot insure a private scooter. When you rent a scooter from one of the apps they come with insurance built in.

Your colleague, and others, breaking the law and driving dangerously does not mean we should get rid of a means of transportation that is legally and safely used by others.
