McLaren racing director Eric Boullier has questioned some of the Red Bull radio transmissions made to Australian Daniel Ricciardo in yesterday Singapore Grand Prix. In the two week break between the Italian and Singapore Grand Prix's the FIA dramatically announced a clampdown on team to driver communications which were deemed to be helping the drivers during the race. Some of the restrictions on teams being able to help drivers with settings on the car and such were deemed legal again in the run up to the Grand Prix weekend, however the increasingly frequent messages this year from the pit wall to drivers coaching them during the race remain banned. The message in question from Red Bull to Ricciardo advised him to help with a battery problem "avoiding exit kerbs may help the problem with the car". One team that took exception was McLaren with Boullier noting to Press Association Sport "We had no issues (with the new radio rules) on our side, It just made us more busy listening to others to make sure they made no mistakes, like Red Bull twice with Ricciardo. I think it was coded, but it is up to the FIA to investigate. It is not for me to investigate. " Red Bull quickly dampened the impact of this however by posting via their Twitter page "The FIA has confirmed to the Team that it's satisfied the messages were related to car reliability concerns, so no coded messages." This is clearly the first flash point of many coming over radio communications although it seems Red Bull has got away with this one. What are your thoughts on their radio transmission's yesterday or the new rules in general?
