I'd guess I see about 40% of RLJers on my London wanderings. I'd love to know whether seeing one person stop has an effect on the riders behind - I'm sure it does have a small effect but without filming a junction over a long period I can't know how big that effect is.
Hi
From what I've seen, it's a very marginal effect, if any. The set of lights outside Kennington Tube are on the main route through South London up to the City and I'd say maybe 60% stop at the lights - there seems to be the ones who've stopped (and not raced to beat the light) and then the ones who whizz by them on a blatant red, they don't seem to be fazed weaving through the stationary cyclists...
