I doubt Kimi would have consented to join a team that stopped him from doing extra-curricular activities – he’s always been a risk-taker. This probably won’t get his relationship with Eric Boullier to the right start, however.
Thankfully it wasn’t too serious. Imagine Renault/Lotus’ position if Kimi had been ruled out of the 2012 season. They couldn’t really have gone back to Petrov or Senna. Time to get Nick Heidfeld in again? :D
