I think Button is considered less of a hairy racer than either Hamilton or Alonso as when against team mates as he would ather finish than crash, the other two will push to a collision to prove a point. I also suspect Hamilton learnt his craft from Alonso during the 07 campaign, neither would give way and wheel banging to a point of shoving each other off the track, now against the rules. Button occasionally has his moments , his win in Canada proves that if he can get away with it he will, on both Hamilton and Alonso. The opposition has to decide whether to push him on the day he decides he can get away with it. The old addage, age and cunning, outweighs youth and enthusiasm
