Formula 1 is set to montior track limits electronically in Mexico, similarly to how they did at the Belgian Grand Prix recently. Drivers gain time if they were to run wide at turn 11 at the Autodromo Hermanos Rodriguez, so an electronic detection system has been put in place to prevent any track extending.
A similar system was used at Spa-Francorchamps to prevent drivers running wide at Raidillon and seemed to work, so it has been brought back again for the Mexican GP.
Track limits has been an issue for F1 for a while now, and a driver running off the track will have their lap time scrapped, with three offences causing them to be issued with a black and white flag.
Sausage kerbs have been used in the past to discourage track extending, but after the scary crash of Alex Peroni in a Formula 3 race at Monza, F1 has opted to use a different strategy.
Race director Michael Masi wrote in his race notes: “On the third occasion of a driver completely crossing the red and white kerb on the exit of Turn 11 with no part of the car remaining in contact with the red and white section of the kerb during the race, he will be shown a black and white flag, any further cutting will then be reported to the stewards.
“Each time any car completely crosses the red and white kerb on the exit of Turn 11, teams will be informed via the official messaging system.
“The above requirements will not automatically apply to any driver who is judged to have been forced off the track, each such case will be judged individually.”
