I voted Prost.
But it was a huge (huge) tie with Senna.
If you take the point of view of the stats, and the F1 as a sport, Shumi is the natural winner of this poll. Probably the most efficient and regular driver. The guy was the dream of ANY team owner. And his carrer and tragic end commands respect.
But...
But if you take the point of view of us, the crowd.
The people that don't see the paddock often.
The people that have a hard time to picture all the sacrifices, efforts and work those teams and drivers have to do in order to keep the F1 circus running...
The people that thrills on a 2h time span that transfigure the sport, where F1 become much more that the sum of his parts like metrics, engineers, drivers, sport, cars, track, apex... When the connection is done and the passion start to rise. When from pure rational science efficiency emerge anger, revenge, stupidity, self-control, daredevil, guts, torn steel, flesh, fire, flamboyance, magic, myth and... death.
Well, only one was the good, the bad and the ugly all in one person.
Only Senna in my eyes represent the quintessence that a Grand Prix victory is, and its price.
So why Prost?
Damn i'm a french *ah* and that guy manage to be on par with Senna and to earn his respect... ^^
