Is it time to start calling out bad cyclists?

Both cyclists and newly licensed drivers require a great deal of experience in order to understand their vehicles and how to not kill themselves and or others, the latter obviously much more highly likely in a car. I strongly agree having a license doesn't make you a safe driver; nor does having little experience and no training make you safe on a bike.
It is a big problem in London; inexperienced cyclists taking to the road and giving others a bad name, and putting their lives at risk. This problem has only been compounded by the Boris bikes disaster which actively encourages complete novices to ride without any knowledge or a helmet!
Police are now out in force penalising experienced cyclists for maneuvers which experienced cyclists know all too well are much safer than what the 'law' requires. All this to fear monger, as a result of deaths resulting from inexperienced and dangerous riding.
London's roads aren't designed for cyclists, yet Boris et al are pouring money into getting as many people out there as possible, regardless of proficiency or knowledge. A big problem I am stuck on as I too desperately want to see combustion engine traffic reduce and cycling increase.
Road attitudes, knowledge and design may take decades to change and settle.
Sigh.

what the fuck does a helmet have to do with it? do shut up
