"I think people underestimate how much work is required when you are the sole supplier, especially as you want to maintain a high and fair level of service. I was working with Ferrari for six years when Bridgestone won four world championships; that was a tough job. But now I am looking after 11 teams, it is much tougher. Along with everyone else at Bridgestone, I am spending more hours at the circuit than ever before."
Much of the increased workload is thanks to a rule change that sees Friday's practice at each grand prix increased to two ninety-minute sessions, the teams being free from the engine restrictions that severely limited their running in the past.That's funny. I don't feel sorry for Bridgestone in the least.
Thanks to F1 Technical for the quote.
