‘I had had a Grand Prix driver teach me to drive. We were on the German autobahn and he said I’d better teach you how to do this properly. The co-founder of Robinson May, the department store chain, had driven the car and been in it a lot with me. ‘“Do it,” he would say to me, “Put your pedal to the metal.” I had it up to 120 mph going through the Mojave desert once. It airfoiled on me: I was shocked. My brother, who was with me, said, “Lift your foot off the pedal, please.”’
