Years ago the famous British racing driver, Striling Moss, coined a scale by which he measured his driving intensity. I'm sure we are all familiar with the term "ten tenths" without necessarily knowing what it means. Moss determined that, depending on the degree of intensity and application in his driving, he would rate it on a scale out of 10. Later this became expressed as a fraction of 1 in tenths graduations. Just driving around rated about 5 tenths and then, in increasing degrees of intensity, the driving effort and application went up until the maximum of ten tenths which was as fast as he felt he was able to go. So, how many "tenths" do we use in our riding, and under what ciorcumstances would we feel it is appropriate to get into the upper scale, the 9 to 10 tenths? How many "tenths" do you feel comfortable with? Do you ever ride at ten tenths? What are the implcations of that decision to you and other road users?
