How did McLaren get it so wrong with their cars in Las Vegas?

As misjudgments go, McLaren’s error in calculations that led to the disqualification of Lando Norris and Oscar Piastri from the Las Vegas Grand Prix on Sunday could barely have been more cataclysmic nor more poorly timed. Quite how they got it wrong just when they wanted to close out the drivers’ championship with as little fuss as possible will take no little explanation.

Norris and Piastri, second and fourth respectively to Max Verstappen’s win in Nevada, had been solid enough results until the FIA discovered the skid blocks on their cars had been worn beyond the 9mm limit. In one fell swoop, Verstappen was right back in the fight, alongside Piastri, 24 points back from Norris.
