Well, yes, some cyclists are clueless. I don't think I've ever seen a cyclist being so stupid as to have *no* road awareness though. Of course some cyclists have a greater degree (than other cyclists) of expectation that car users will take action to avoid hitting them - actions such as *looking for cyclists* before turning out of a side road or drive way.

I've not seen a multi-car pile up result from a cyclist Doing Stupid Things; I don't doubt that it is a theoretically possible outcome. But I do live in Stupid Cyclist Central so I think that the probability of such terrible outcomes is experimentally fairly low.

I have had many cars do things that were directly dangerous to me - like overtaking inches from my elbow (what if I wobbled?) or tail gating.
