Given the recent incidents at Brands Hatch and the Hungaroring there couldn't have been a worse time to send bits of car flying across the racetrack, so its no surprise that the Renault team has been hit with a punitive penalty after this afternoon's pitstop chaos.
If you didn't see the incident the details are that Alonso's car was released from the pits before the right front wheel had been properly attached leading to first the aerodynamic finisher and then the wheel itself parting company with the car and bouncing down th track.
After investigating the stewards found that the Renault team had knowingly endangered their own driver and other entrants by failing to warn Alonso and making no attempt to stop the car leaving the pits or stop it out on the track. As a result the team has been banned from the European Grand Prix in Valencia, which will go down well with Fernando Alonso's home fans. Or possibly not.
Renault will launch an appeal, however I hope its unsuccessful, not because of any dislike with the Renault team, but to ensure that this sort of thing is treated more seriously in the future.
