There's a legend of Ronnie Peterson doing the old Silverstone-track blindfolded. This should have happened during post-season testing in 1973. Legend has it that Ronnie did it on his own by simply demonstratively pulling down his balaclava in the pits, still clocking within 10 sec of his best.
This was obviously done in order to mock Emerson Fittipaldi, who was pissed off no end by this bizarre spectacle, while Colin Chapman and Peter Warr were laughing their asses off.
Result was Emerson walked off to McLaren.
Anyone with any kind of info on this?
