8. Doors off – Formula 1, Interlagos, 2002
During the warm up session before the 2002 Brazilian Grand Prix, Enrique Bernoldi had a crash in his Arrows. As the medical car rushed out to check he was OK, Nick Heidfeld came steaming around the corner and, spotting the Mercedes E-Class parked up right on the apex, slammed on the brakes of his Sauber. He locked up, careered out of control and smashed the door off the medical car just as it was being opened. Luckily, no one was hurt.
