Stuart,
I'm surprised you would provide such incomparable data to support your assertion that cars jump red lights more than bikes, and that you quoted the figure of 30%.
Although I have not seen the methodology for the RAC survey, the 30% figure seems to include drivers going through a 'last-minute amber signal', which I do not believe the TfL study of 6 London intersections included.
A better study, if you want a comparison, is

At Trafalgar Square, researchers spotted 117 road-users charging through lights after they turned red over a three-hour period. Fifty one were cyclists, 13 were motorcyclists and 23 were car drivers.
Eighteen vans shot through on red, as well as four police vehicles not on emergency calls, three lorries and five buses.
The survey was repeated at other locations in central and outer London with similar results.
According to these statistics 44% of red light jumpers were cyclists and 20% were car drivers. So this particular set of data would suggest that cyclists are more likely to jump red lights in absolute terms and much more likely in proportion to the numbers on the road.
Where I have no disagreement with you about is that drivers who jump red lights are a more significant danger to other road users and to themselves, but that should not excuse law breaking by anybody else.
In the last few posts you have claimed that personal observation is no substitute for good statistics, and again you have no disagreement from me. But I await to see some good statistics on red light jumping, until then I think most of the people on this forum will be sceptical regarding your claims that more motorists jump red lights than cyclists.
And I feel that this focus on cars jumping red lights is just a distraction from the issue that most posters on this thread have with pavement cycling, which you seem unwilling to consider as any type of problem however annoying many posters perceive it to be.
