…which is why we should have neither.
Actually the Top 10 rule would do what it’s supposed to if we didn’t have the mandatory pit-stop. It even makes sense – given a choice of tyres to start with, the front-runners would all go for the hard, cruise around for 40 laps, and then pit for softs at the end. Thinking about it though, that would be better, because the latter stage of the race is usually boring anyway, might as well have the pit-stops then – the problem is that field would probably be too far spread out for anyone to pit early and charge around for 2 laps and leapfrog their opponent.
Sorry, this was about KERS! Which as a push-to-pass I detest.
