Interestingly, that actually touches on the main issue here (basically, lawbreaking). For many years, cycling in/around London was essentially the preserve of the fit and the foolhardy - the only people happy duelling with buses, lorries etc which narrowed the demographic overwhelmingly. And the only behaviour that would help you in this was risk-taking. Jumping lights, hopping pavements, most of it was simply survival rather than a conscious desire to break the law. Most people have a very good moral compass around laws, etiquette etc (although when it comes to road use, that often breaks down with "minor" offences like speeding, pavement parking, yellow box infringement etc so common that no-one even bats an eyelid). However, gradually that picture is changing. Congestion charge, hire bikes, tube strikes, economics and more cycle infrastructure have put more people on bikes. That infrastructure however is the stumbling block. Built to no national standard, often as a tickbox exercise in "green transport", it is actually directs cyclists to ride on pavements or to ride up the inside of queuing traffic (both things which your old cycling proficiency test said "DO NOT DO THIS!") and I can cite numerous occurrences where a shared use foot/cycle path will evaporate in the middle of nowhere leaving a rider completely abandoned in the middle of a pavement or dump a rider out into the middle of a junction. Have a look here for some wonderful examples of what passes for "infrastructure" here in the UK: http://homepage.ntlworld.com/pete.meg/wcc/facility-of-the-month/index.htm Most people do acknowledge that they have a responsibility to themselves and others its just that when you're vulnerable and surrounded by tonnes of steel, you very much tend to look out for number 1. And cyclists really don't want to it anyone or anything themselves. Whether or not they care about anything else is irrelevant; if a cyclist hit someone or something, they'll fall off, end up hurt and their bike might end up damaged so they really want to avoid that! Slight tangent to the OP but there is a much bigger issue here than simply some cyclists being reckless (although yes, that is part of the problem in the same way that a speeding driver is reckless).
