All these experts know nothing, it's obvious to everyone that Bruno Senna is the best driver of the season... 
I disagree with Mark, Lewis shouldn't be #1 because he has made a number of mistakes that were of his own making, and (I know RC won't agree) childish outbursts over the radio when things didn't go his way. Same goes for Fernando, too many mistakes and losing his head moments. I believe driver of the season has to go to either Robert Kubica or Nico Rosberg, both had under-performing cars and managed a number of podium finishes while comprehensively outperforming their team mates.
myownalias just when did Lewis make a ''lot''of mistakes, the only one that counts imo is monza, in singapore he was going for it like he always does, and suzuka didnt cost him because he would have been 3rd if not for the car!, plus what about vettel, remember hungary?, hands up and down the pit lane?, but i do agree that kubica and rosberg were some of the best drivers of 2010, anyway dont worry lewis your always my number 1!
Further to this, myownalias, you say they both comprehensively beat their teammates!
May I remind you, the qualifying stat for:
Lewis-Jenson : 13-5
Nico-Schumi: 13-5
Is equal.
Lewis had 'car' retirements in:
- Hungary - Engine - (while 3rd?)
- Spain - Suspension failure (1 lap away from finishing 2nd)
- Japan - 4th, then gifted 5th to Jenson due to gearbox
Jenson had 'car' retirements in:
- Monaco (while in 5th)
Points difference at the end: 26...discounting the misfortunes of both drivers!
