There were a total of 1200 possible track limit breaches during the Austrian Grand Prix. They were occurring faster than race control could keep up with and although several penalties were applied either in the race or immediately afterwards, after several hours of race control scrolling through the footage the official results were quite different to those across the line. The podium finishers were unaffected but the remainder of the pointspaying positions were wildly jumbled up.
The main problem was the fast Turn 10, the final corner on the lap, taken in fifth gear, downhill and with a dip in the middle which tends to pull the cars out wide. The track limits are defined only by a white line and drivers were reporting that it was impossible to see that from within the cockpit.
