I once heard that Stirling Moss himself was asked the same question after going rather fast through the Mersey tunnel.In remember some years ago on the A1 southbound I was stopped by the traffic police for going a tad over the speed limit the bobby got out of his patrol car strolled over and said (you've got it)......................
"Who do you think you are, Stirling Moss?".
I have just read that he completed the 992 mile Mille Miglia in just over 10 hours in 1955. Incredible.
