Trying to maintain "too" high of a level of attention will result in an earlier, steeper "drop" following it. Our only choice is to drive with a high but reasonable level of attention focused at driving, and choose to increase/decrease it depending on the conditions. Within such a normal level of attention, the drop is experienced after 40 to 50 minutes (much like at a class in school), and that is part of the reason why I recommend my trainees to perform hourly breaks in drives of two hours and more.
It is interesting that many (advanced) tests in the UK last for approx 90 minutes.Astraist wrote:Mere experience in driving, even outside of an advanced driving tuition, offers the human mind (which works like a muscle in training) a chance to synchronise itself with the unique cognitive demands of driving and allows to take in more usable information based on a given level of attention. i.e. we can either adapt our attention level to take in more information, or increase our analitic ability of making more out of the given amount of data. The exact blend of the two is where every driver differs from the other.
Would this be similar to having different kinds of concentration. The more adept you get at driving at a particular level the more you can apply, what I would call, 'relaxed concentration'?

Thank you, Brian: that last bit gets my vote.
Surely what we want is a style that produces a satisfactory level of concentration on the important issues, and in a form that is maintainable comfortably for long periods, preferably aided by a 15-20 minute break every two hours in a really long journey.
I still can't go along with the notion that 100% concentration on the driving task is necessary at all times.
When I had my part time job delivering new cars I never knew what time I would get home, so I used to ring Eileen when I was about 15 mintes away and let her know how I was getting on. There is a section of road on the A169 that includes a long straight section almost a mile long, slightly uphill and with one farm entrance about halfway along on the right. That road was virtually free of other vehicles at the times I was travelling, so I felt it was quite reasonable to pick up the phone, press a couple of buttons and say "Hiya gorgeous, I should be back in about 15 minutes" or words to that effect. The whole thing took no more than about 15 seconds.
Now then, which of you '100% concentration at all times' people (who I trust are considerably better than average drivers) really believe you can't divert sufficient attention away from the driving task to manage that - or similar brief distractions - safely?
Best wishes all,
Dave.
