Tiny Lund was by no means any athlete and he did well in 1964. But when the power steering goes out now, just look at how it affects the drivers performance, especially if it goes out early in a long race. Also they have to get used to the difference in brakes. The open wheel cars have great brakes while you can't stop one of these cars immediately. I remember a few years ago, forget which race it was, that Ricky Rudd won and they had to lift him out of the car and carry him to the medical room as he was out from heat exhaustion. The cool suites are great but if they fail they are worse than not having one.
