Two F1 questions/points (spoiler included)

Grosjean got a drive through today for overtaking off the track but he clearly didn't do that, in fact all four wheels were on the track when he went ahead of Massa. In previous races I've seen the commentary team specifically looking at whether the nose was in front when the wheels left the track and in this case not only were two wheels on but all four were, he was half a car length ahead when he finally left the track.

Secondly Webber on fresh and faster tyres was coming up behind Vettel in the closing stages of the race when both Vettel and Webber were given the radio message 'Fail 22' which the commentators took to mean they had a problem with both cars. Does anyone else think that rather than being a problem it was actually team orders and was the opposite call to 'Multi 21' meaning that Webber was to stay behind Vettel and not challenge him? He certainly dropped back after being given the call while Vettel continued to push.

 

I think it was for the earlier overtake when he and Button touched and he had to go across the escape road.

Correct me if I'm wrong.

 

The overtake on Button was at turn 6 and the message from Race control was 'incident involving Car 8 (R. Grosjean) under investigation - Leaving the track at turn 4' so it must have been the Massa overtake (which happened at turn 4). I believe that 'causing a collision' with Button is investigated after the race
