nah he was just talking rubbish. Aussie always do.
What he was referring to was the high speed blow outs the Michelin tyres were suffering a few years ago, which forced all Michelin cars to pull into the pits and retire without even starting the race. And that only happened because the oval part of the track have been resurfaced, and the track surface was much more abbrassive on the tyres than Michelin estimated.
It wasn't a problem for Bridgestone because they got data from the Indy 500 (they supply tyres to the IRL).
But 24 F1 cars going round Bristol for 400 laps would be brilliant!!
