*Disabled* I understood (so there was nothing to ignore).
It depends how 'open' your mind is (or is willing to be on something). ;-)
The parallel was that 'in some cases' the driver of a vehicle is no more 'in control' than someone on a roller-coaster or driving a train.
If something appears in front of you there are a whole manner of variables (some out of your control) that then determine if you hit it or not. In some cases 'target fixation' being one of them.
So, do something regularly enough (like cycle round a circuit) and then change some of the variables (put a car where cars shouldn't be, be blinded by the sun or a headlight directly or the reflection from the wet road) and combine that with what is a very normal and generally managed 'distraction' (glancing away from the road ahead to check the radio, clock, speedo, GPS etc) and it can all conspire against you.
I'm not condoning what the cyclist was doing because I wasn't there, I'm just suggesting that these things can happen and to the best of us? 'Chaos theory'.
