During the Brazilian Grand Prix of 2012 Kimi Raikkonen got lost when he went off track in the 52th lap op the race. He later said he knew a shortcut which he used back in 2001 as well.
Kimi Raikkonen: “Where I went off you can get back on the track by going through the support race pitlane, but you have to go through a gate. I know this as I did the same thing in 2001 and the gate was open that year. Somebody closed it this time.”
