I felt confident at 24, but I am a better driver now.

My father did everything for me. He was awesome.

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 look back and you remember the good, the bad and the ugly

When I do retire, I know for a fact that I'll never be able to replace the incredible feeling I get when I'm driving an F1 car.

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.

If I ever have a son, and if he wants to follow in my footsteps in Formula 1, my main responsibility will be to point out some of the negatives.
