Formula 1 is producing a season of great racing, so I don't want to appear to be having a moan. But there are several things arising from the German Grand Prix that the powers that be must take a long, hard look at.
Brakes were a big talking point at Hockenheim, with Lewis Hamilton's crash early in qualifying and subsequent question marks over the changing of brake material.
It's becoming a very serious issue: this season, we have witnessed more brake failures of one sort or another than we have for many years. As someone who was responsible for the safety of my F1 cars on track for many years, let me assure you that any failure relating to the brakes is one of the most serious a driver can encounter.
