These threads of, off camber/reducing radius/car in my lane/cold pavement.... always remind me of a canoe lecture we went to. A well known white water guru was being pressured by a weekender on how a certain rivers rapid section would be rated on the 1-5 class. Lecturer asked "did you fall out of the boat?" reply was "well yes" ... lecturer "then that's a level 5 for you then isn't it"
