I remember seeing him drive with a golf ball in a saucer on the bonnet of the car... the trick being to drive so smoothly that the ball stayed in the saucer. Needless to say he could.
That was 'Formula Finesse' back in the early 70s?
I was at Brands Hatch for one of the first sessions, in Ford Consul GTs, courtesy of Ford.
We were taken round the Club circuit, 3 passengers, with an 'expert' driver, showing us how it was done. Then we all went round individually, with an 'expert' passenger.
I think the balls were bigger (somewhere between golf and cricket ball size) and softer than golf balls - Anyway, they quickly ran out of balls and we had to walk round the track picking them all up, before we started again (Maybe they later replaced them with more freely available golf balls for the subsequent days?) If you ran over a ball, it got squashed.
A few of us lucky ones had JYS as our instructor, and he wasn't too impressed by my efforts, as I recall! He eventually got me to do a complete lap without losing my ball - But it probably took me 4 minutes!
I did get the point of driving smoothly being quicker, but questioned the ball and saucer thing with him, and wondered how many balls he would have lost during his then recent win at the Nurburgring! (Think it must have been 1973 then)
