Nelson Piquet was on course to win the 1982 German GP until he was baulked and taken out by backmarker Elizio Salazar. Never one to walk away quietly, Piquet went after him with arms and legs flailing. Salazar was lucky he hadn't taken off his helmet until after the marshals separated them.
Gachot makes ‘em cry
You can't make up stories like this. Just before his home GP in Belgium in 1991, Bertrand Gachot landed himself in jail in London for assaulting a cab driver with a can of tear gas. His replacement at that race, however gave a fairly good account of himself. A certain Michael Schumacher.
Senna needles Prost
After lapping nearly the entire field at the 1993 European GP, Ayrton Senna made Alain Prost stop complaining about his car as he was lapped by Senna en route to victory with one line; “would you like to drive my car instead?”
Schumi’s red mist
Michael Schumacher was on course to win the very wet 1998 Belgian GP until he came up to lap David Coulthard's McLaren. Unsighted by the spray, the German rammed into the Scot, taking both out of the race. Furious at the turn of events, Schumacher made his way back to the pitlane and had to be kept away from Coulthard.
