As the events of the last race of the season unfolded at Interlagos, twitter became awash with criticism of the stewards decision to levy Felipe Massa with a drive through penalty. The Brazilian was himself none too impressed, gesticulating as he passed through the pitlane to serve his penalty after he'd already told Rob Smedley (his race engineer) "This is unacceptable, this is unbelievable, unbelievable, unacceptable" in an exaggerated tone.
The fact however remains than prior to the start of the GP weekend the teams and drivers had been given the following instructions:
Not shown in the picture above but a separation in the line before the juncture with the hash markings was also made on the track to define this limitation. As we will see in the next few images all the drivers skirts the pit entry line at Interlago's as it opens up the corner and allows a quicker exit. Massa however stepped over that line much further than any other driver I can find footage of.
Anyway for those that prefer to see it in motion rather than in pictures
As far as I'm concerned it's a stonewall penalty, did others do the same? That I cannot tell you, but from the footage I have they didn't.
