So let me get this straight, you disappear for about 5 days and then reappear and answer so quickly my super hard question?
Just kidding.
Yep, that why. Although I believe Lauda was running third, with a couple of laps to go, when one of his tires started to let go. Time for a mad dash Ferrari pitstop, which was duly done, and he left the pit lane like a rocket...
Or at least he would have done, if it wasn't for the fact that the pitlane exit was blocked with several dozen officials, a number of corporate guests of the RAC, one or two pitlane marshals all spectating, none of them anticipating a car exiting the pitlane at this late stage of the race.
Oh, and some were even using a Ford Cortina course car as a grandstand, so even if people had moved out of the way, the car would still not have been able to get by.
As a result, Lauda, trapped in the pitlane was classified a lap down - and ninth.
Naturally, it went to arbitration, and six months after the event, it was decided he had a realistic chance of being on the lead lap, and so was awarded fifth. Two points.
nice anecdote... OK, wastegate... shoot
