THIS week’s French Grand Prix is about to get incredibly political in a row over rules. Yet while some teams (mainly Red Bull and Ferrari) have mastered their designs, others, such as Mercedes, haven’t and the flow of air under the car’s floor caused the car to oscillate. There is also a distinct feeling that the FIA’s intervention goes against the spirit of the regulations and that a governing body has no place telling teams how to set up their race cars. No wonder some teams all think it is all rather murky, especially as the waters are already muddy. Now they have terminated a deal with the motorbike team – via Twitter. Lawrence Stroll will retain a controlling stake in the team as he juggles the team’s F1 operation and luxury sports car business.
