F1 has always been a competition fought alone the lines of "technological warfare", each team has to make a unique car made under a set of stringent rules. The performance difference is in the region of 1.5 seconds in a typical lap of 75-90 seconds i.e. less than 1.2%. The competition of the F1 grid is considerably closer than other race series in which the competitors use identical cars.
Many contributors here are Button and Brawn bashing claiming they have an illegal car, one which is so fast that people claim Button will walk through the season with no threat.
Firstly, we should be championing a British team and engineers that have made a car that is superior to all the other major competitors with a lack of time for testing and adapting the original design. In addition, Brawn is not leagues above the rest.
Such is the pace of change that, were a car to win the first race of the championship and not be developed in any way, it would be lapped and be last by the end of that same season.
Brawn must continue to advance the design of their car with far less funding than their major competitors, and Button must keep his driving as consistent as it was in Melbourne if not better.
This championship is not decided, BrawnGP's future is not decided, and the ball is now in the other constructors court to make the next move. The change in the rules have left the door wide open for technical advancement, KERS is such an undeveloped system we have plenty of time for this entire championship to be turned on its head.
