I'm not concerned about other drivers assessing my speed; leave that, and my being aware of other vehicles, to me. I just want the idiots to know I'm there, and in daylight main beam is much better for that than dipped beam.
Yes, but it does (or can) antagonise and worse, distract. 'Target fixation' if true - is a risk for you here.
As a car driver, I'd prefer to be concentrating on my driving rather than having to deal with being dazzled. As a biker, I've always found dipped beam sufficient.
Makes you think, though, doesn't it? Apart from the fact that my headlight would have been on, if I had been the biker I would probably have been doing the same sort of speed, and would have had the same accident. I don't think consciously about the risk of an idiot coming out of a bend on the wrong side of the road, I just assess that risk as very small and accept it.
Good summary of what we all face every time we venture onto the roads - irrespective of vehicle we are piloting.
