In the book, Proficient Motorcycling, Hough theorized that this statistic is due to familiarity with the roads and a lack of respect for the dangers.
"I've gone through this intersection thousands of times and noone has ever blown it..." All it takes is once.
I am just as guilty of this as anyone.
I have been doing my best to try and treat the streets of my neighborhood and towns as the dangers they truly are, but it is so easy to slip back into complacency. ATGATT helps, though by no means mitigates, the dangers of mistakes.
I wear the best gear available, but I try to ride as if I were wearing t-shirt, flip-flops, and shorts.
Statistics are good because they give you information on what happens to average people. We can easily beat the statistics, but only if we recognize them for what they are and use the information.
It is a poor general who discounts inteligence. To discount this statistic without doing something to address it, leaves you just as open to becoming a statistic as you were before.
