Day before yesterday I nearly killed myself and another rider. In the end we just avoided a head-on, each going on his way without stopping. I was engaged in a series of very nice twisties on a fairly deserted Scottish road. We had been riding for about an hour and I really felt 'in the groove'. I probably relaxed concentration for a moment because I went into the next left hand bend just a wee bit too fast. Almost as soon as I realised I was was too fast another bike appeared going the other way. His track through the turn was close the centreline. The danger was imminent and extreme. At this point I committed just about every newbie error including braking and looking at the oncoming bike. We missed but only by about 2 ft. I have done track days and I know enough to know that I should have fixed my gaze hard into the turn and leaned more. Now here's the thing. I am sure that if another bike had not been approaching, this is exactly what I would have done. But the bike represented a huge threat and so I target fixated on it. I hadn't thought about this before but the natural human response when detecting a threat is to fix attention on it. It is very unnatural to look away from danger. Of course you don't get to practice overriding this natural instinct on a track day. Unless you want to try going round the track the wrong way!
