The notion of 'world leadership' is a curiously archaic one. The very phrase is redolent of Kipling ballads and James Bondian adventures. What makes a country a world leader? Is it population, in which case India is on course to top the charts, overtaking China as the world's most populous country by 2034?

I don't think KERS will change the overall picture - the gaps between the teams won't get any bigger. And I don't expect more overtaking, especially not under braking. The braking distances of modern F1 cars are just too short to make a big difference.

An argument is an indication of a person's ego overtaking his logic.
