"I've had a few crashes in my career [and], once you've experienced something like that, you never lose the fear that it might happen again," he conceded, "To drive an F1 car you have to be a little mad. On the morning of a race, there's a mix of excitement and fear.
"If it's a wet track, then it's worse as you're not in control most of the time, which is the thing all drivers fear the most. You go down a straight and there's a wall of spray in front of you. If a car has crashed in front of you, you're going to hit it at 200mph.You'd have to be stupid to think that everything is always going to be all right. If anything, the fear intensifies as you get older but it's a hard thing to give up.
on my mind [but], in any sport, the trick is to retire at the right time. So many drivers say they look forward to retiring from F1 and they can't wait to live a more leisurely life - but, after four months away from it, they go stir crazy because they miss the constant buzz. I've still got ambitions within F1 - another championship would be a fantastic achievement."
