Sorry red but I disagree.
Admittedly, Shumis's last world crown was won in the best car by miles but he did win at least 2 of his championships with Ferrari in an inferior car.
Yes ,Senna could have been a match if he had not met his early dimise but none of the current crop of drivers has his skill or level of determination.
He really is the ultimate racing driver and the only one in my opinion who has the talent to know how to drive on the limit but not cross it.
The likes of Button and Alonso are too cautious, Montoya is just a loon, Raikonnen is hungry, but the car isn't good enough and the rest have no chance.
I would say that 7 world chamionships in 12 years, coping with all the rule changes, new drivers competing in an inferior car etc, etc. surely qualifies Michael Schumaccer as one of if not the worlds greatest drivers.
