Brawn F1 - the ultimate in one-season wonders.

Very true.

The only way they could have surpassed it would have been if Rubens had made second rather than third in the championship.

I wonder if they'll keep the luminous green and white livery: it certainly made them very visible on the track. I suspect not, sadly.

I wonder how Button will cope with a team mate who not only can beat him but wants to beat him every time, generally thinks he is sitting in his chair and gets paid more than twice as much.

It could be very interesting indeed.

It's certainly a real game of musical chairs this year.

I'm trying to remember if typical McLaren car characteristics suit Button's style.
I suspect not.

On the other hand, Hamilton has just about got used to the go-faster button, and will now lose it again, while Button won't have to unlearn that.

Button's driving style is famously very smooth, which may help preserve fuel and tyres - quite useful when refuelling isn't permitted.
