perhaps a mutant side note; last year a very good friend took his motorcycle trip of a lifetime (we both retired) to a place called the ‘Tail of the Dragon’ NC/TN USA (a very dangerous place due to very crazy people). This person is a riding fool and traveled the 1200 +/- miles in a lot less than a day and a half, he arrived mid morning and the last thing he told me he remembered is having to pull over quickly then, as the story goes, 72 hrs and a $42,000 USD helicopter ride later he was coherent (relatively speaking) again. Seems he decided to count the lines/poles to occupy travel time and induced some sort of grand type of seizure.
Any relevance other than the lesson that all should not travel at high speeds over vast distances on a bike whilst trying to count rapidly disappearing lines and objects ?, you tell me……….
