Well, my experience of cycling from Waterloo to Bank several times a
week is that at least 75% of cyclists go straight through red lights.
If the same numbers applied to cars, then 75% of the time, a car
arriving at a red light should jump it. This isn't even remotely the
case.

It's about 50% here in Cambridge I estimate. And a bit less for cyclists.
