With regards to the RLJ issue, I was thinking about the excuse for RLJ'ing that some people come out with about how they RLJ because it's 'too dangerous not to'. If you feel so endangered, there are a number of solutions that don't involve breaking the law:
Get off and walk it past the dangerous bit
Pull over and let the dangerous traffic pass
Find an alternate, safer route
I cycle through some of the busiest parts of London in rush hour every day and I have not once felt in danger stopped at a red light. There are a couple of occasions that I'll pull over and let heavy traffic pass or walk it round a dangerous bit, adds an extra minute or so to my journey, big deal.
