Lewis's problem with the stewards stems from the fact that he saw Michael Schumacher coming and had the good sense to avoid an accident at the hairpin. He cannot understand why other drivers don't attempt to avoid accidents, they appear to him to prefer to crash than race and have overtaking in F1.
Michael Schumacher used to deliberately close the door too late and eventually the stewards cottoned on to the fact that he preferred to take people out than be overtaken. They clarified the rules and started penalising drivers who deliberately closed the door, preferring collision to being overtaken. Recently the stewards have reverted to penalising anyone who attempts to overtake and ignores the fact that the guy in front does very often have a choice.
