In my area of London, I'd say 80-90% of cyclists think red lights don't apply to them. I've even been sworn at by another cyclist for stopping at a traffic light.

The illegal ebike users are the worst. My ex saw one hit a woman with two kids, because he just zoomed past a red when it was green man at the crossing.

Cyclists are the reason I've gone back to public transport. I actually felt safer on my cycle commute on the high road with cars, than I did on dedicated cycle lanes 😞
