Sir Jackie Stewart doesn't understand why drivers don't use coaches

Sir Jackie Stewart has revealed he does not understand why current drivers do not utilise coaches more as well as speaking about his own development.

Stewart won three F1 World Championships in 1969, 71 and 73 as well as competing in the Indy 500 in 1966.

‘The Flying Scot’ has been a supporter of coaching in F1 and he believes it helps the drivers not only physically but mentally.

"I simply don't understand it to this day,” said Stewart to Autosport.

"There is not a single driver at the highest peak of his skills who would not be assisted by wisdom and observations that he probably had never thought of.

"Now they [F1 drivers] are fit and they have coaches to help them with their physical condition, but not their mental ability.

"And I think that's completely wrong,” added Stewart.

Stewart recalled how Jim Clark was one of many people he learnt from as he started out as well as learning from his rivals.

"I was so hungry to learn from other people and I was lucky I had Jim Clark to talk to.

"He was the best racing driver I ever raced with.” Added the Scotsman.
