I need to develop a car and engineer a car in a position that feels comfortable for me, and I don't think anyone can do a better job than I can in that position. The problem for me is if I can't get the car there I do struggle more than some.

I don't purposely speed, but I might go over by five or six miles an hour from time to time. It doesn't give me a buzz driving on normal roads, because I can't go fast enough. It's never going to be anything like an F1 car.

When I'm on my own, I can be negative. I need my friends and family around to help pick me up if I've had a bad qualifying session. I think insecurity plagues a lot of sportspeople.

The fast, flowing parts, the high-speed corners, that's where a Formula One car is at its best - changes of direction, pulling high g-forces left and right.

For me, triathlons were something that was down to me and my fitness. Now, I really enjoy the pain in the triathlon of chasing someone down. It's a bit like chasing down Nico Rosberg in the last few laps at Silverstone - it makes you feel alive.

We all drive differently and have different styles. For me I need a car I can develop beneath me and feel comfortable in. If the car feels neutral and unbalanced it doesn't work for me.
