Well it's going to be one of those people you do f*** off in that 5% of time that will probably be the literal death of you. I have had cars swerve at me, follow me by centimeters, pull along side and literally try and force me off the road and my crime was normally jumping the queue by filtering - safely - at a set of lights. People do not realise or care that they are in a literal death machine and as a biker you are so vulnerable already so why try to piss off people just to boast to some people on the internet? Surely you arriving home to your family rather than a couple of policemen turning up at 1am should be everyones goal here. If you are poo-pooing Bike Safe, get yourself on a track day learn how to ride at speeds in a safe environment and keep it there rather than on the roads.
