I said undertaking was dumb pages ago, but dumb doesn't equate to risk. My point is that the risk does not lie with the actions of the cyclists, but with the type of vehicle, and that the false analysis of the risk by people like you is ignorant.
And, actually, there is a great deal you can do if you hear a truck coming up behind, starting with looking over your shoulder and checking out the truck. I've been riding around London for 45 years, and there's not a lot that scares me, but if I see a tipper truck or a skip lorry behind me then I head for safety.
it does equate to risk if you don't know what the risk is. That's what I'm saying... That the cyclist doesn't understand the risk... The risk that lays with the vehicle and driver. And how can they avoid it if they don't know? You're having a go at me for wanting to educate cyclists, Yet you admit you wouldn't be "dumb" enough to ride up the side of one, you tell your own group not to ride up them and you admit you head for safety when you see one? Its completely contradictory. I never said there were no other risks, like lorries coming up from behind, or cars hitting cyclists, its not a false analysis just bcoz you talk about about one element of danger.
