I was going to mention Clark's racing in other series, that's why i said he was flexible. He's definitely one of the greatest; not "The" IMO, but one that stands out. His speed more than anything else is what i notice; i'm not sure about other subtleties. I got the lotus dvd set, i have't watched it as yet though.
Button can't improve anymore than he has already. He's 30 years of age with 10 years in the game.
His tyre problem is just part of his natural limits. It is present no matter what changes are made.
In race and in qualifying Hamilton is comfortably ahead. Hamilton can even preserve the tyres better, becuase he seems to understand them more.
I don't think Button has been disadvantaged by this year's tyres in a big way, unless we are assuming he's better than he is. Or he gave us the perception he's better than what he's showing us this year. A good driver should learn how to deal with every challenge that presents itself.
Before the beginning of the season, it seemed this reasoning was generally accepted, and Hamilton was the incomplete driver without the skill to save tyres.
Now that myth has been debunked since we've witnessed that adaptable drivers adapt to more than the feeling of the car, but also to tyres and regulations better.
I see this tyre problem more of a confidence and comfort issue than driving style. Button has all the telemetry to figure out what Hamilton is doing with the tyres. He may be reluctant to switch up his approach to driving, or it's possible he risks losing control if he drove more on the edge.
Autosport used the word gamble to describe Button's Brazil approach. I hope it works out for him. Another Korea race is the last thing he wants.
