I just love the Schumi haters who claim that he's ethically inferior. Have you guys not forgotten that the hallowed Senna and Prost were both very well known for their ruthlessness, especially Senna? Those two guys were team-mates at McLaren and each took the other out in order to clinch the championship. I believe this happened in succeeding years but I may be wrong about that. I know Schumacher has tried that on a couple of occasions too, which shows that he can also be ruthless.
All three of them have shown a lack of respect for their fellow competitors and believed that others should simply get out of their way when approached from behind.
I believe that had Senna lived he would have been as vilified as Schumacher is now. However, he died while racing and that seems to have elevated him to can-do-no wrong God status. Senna was widely disliked by the other drivers around him while he was alive, however, that does not take away the fact that he was one of the best, if not the best, drivers of all time. Period.
I think a certain ruthlessness will be found in the best competitors in any sport.
By the way, I consider Alonso to be the quickest driver in F1 today and it seems he's going down the same path as Senna, Prost and Schumacher. He's already demonstrated a certain sense of superiority out there to his fellow racers. He get's very impatient when others do not step aside right away.
