Re red light jumping, it has been suggested that like car drivers, some cyclists do, and some don’t.
Stand at any junction with traffic lights in London, and you’ll see that it’s more like some cyclists stop at a red light, but the vast majority don’t, while with vehicles, it’s almost every one of them stops when the lights are red, but occasionally one or two don’t.
So yes, some cyclists ignore red lights, like a big percentage, while one or two cars will run a red, but almost all cars will stop.
