none for me, as I showed a week ago in this thread. he was actually given too much chances to improve, and I think he was very lucky to have survived in 2008.
With him still only getting 15th place in qual while Alonso snatches pole and now all the mud-slinging afterwards it was obvious - I'm actually surprised it took a whole week...
The difference is that at no moment Senna is ahead of Prost while Villeneuve was clearly half a car ahead and had already passed him on the inside when Herr Arschloch tried to wreck him.
Now let's count and compare how many dirty moves and, more important, deliberate attempts of wrecking have been done by Prost, Senna and Schumacher all along their respective careers.
Senna effectively had the corner. It doesn't matter at that point whether he's level with Prost or half a car length ahead. Prost isn't going to stay around the outside of the first part of the chicane.
Fangio, Farina, Clark, G.Hill, Rindt, Peterson, Hunt, Stewart, Brabham, McLaren, Surtees, Moss, Nuvolari, Stuck, Rosemeyer, Alan Jones, Piquet, Patrese and Mansell. The list is endless. They were all amazing. And you're telling me one of these drivers won't creep into someones top 3? There will be one, and there are ones I've missed too, Lauda, Rosberg, even Nicola Larini and Gehard Berger for christ sake.
How can you argue that Schumacher isn't the best driver to date? Even with '94 off his belt, he still is the most successful driver. Generally if you are so sucessful at something you are the best at it. You don't say 'arguably' if it's a fact, because a fact can't be argued, a fact is a fact and it can't be changed or be opinionated.
Stats aren't always an indication of who is best. They can be an indication of what drivers are in the best cars (the two don't always go together) plus a lot of stats don't take into account things like season length (there used to be only a handful of races in an F1 but now there are usually 16+) and reliability (there's no good having the best driver in the best car if you can't finish a race). Then you get to how each driver achieved their success. Drivers like Fangio, Hawthorne, Moss were some of the best in their time and there are no stories of them taking out rivals just to win a race or a championship. Schumacher is statistically the most successful driver, but that doesn't necessarily mean he's the best.
also don't forget that the improvenments in safety can make the stats uneven. if the cars were still built to the standards of the 60's, 70's or possibly even the 80's then almost certainly schumacher would have only won 2 titles at best and would be remembered or being killed at silverstone in 99 and hakkinen would never have won a single race having died in australia. conversly lauda would probably have won the 76 title if his crash had happened in one of today's cars.
