As you get older, you do reflect more. They were great times, but the biggest thing we all had to deal with a lot more disappointment from an engineering point of view, there was not the reliability that there is now.

Motor racing is 99 per cent downs and one per cent ups. It's a huge challenge, as there are so many things that can go wrong.

It seems to me a lot of drivers have lost their personalities or are not able to express themselves. However, it's a very commercial market, and manufacturers have a far bigger say than ever before.

I was a driver and a racer. The difference between drivers, who can be great World Champions, and racers, who are also World Champions, is that racers don't wait for things to happen: they make things happen.
