FYI, this from the Grand Prix Drivers' Association:
We trust that the changes made to the tyres will have the desired results and that similar problems will not occur during the German GP weekend.
We are ready to drive our cars to the limit, as we always do, and as it is expected by our teams, sponsors and fans.
However, the drivers have decided that, if similar problems should manifest themselves during the German GP, we shall immediately withdraw from the event, as this avoidable problem with the tyres endangers again the lives of drivers, marshals and fans."
You know some will race anyway. Pass the popcorn.
