It is not always possible to be the best, but it is always possible to improve your own performance.

It takes leadership to improve safety. And I started off the movement in my time, but the person who has done more over the past 20 to 30 years and who has led it is Professor Sid Watkins.

The years I raced in were fantastic. There was so much change in the cars. We went from treaded tyres to no wings right through to slicks to enormous wings.

In one year I travelled 450,000 miles by air.

Oh yes. It's not when you brake but when you take them off that counts. Most people don't understand that.

From the five years, 1968-73, if you were an F1 driver at that time, there was a very likely chance that you would have died.

When there is an accident involving fire, in most cases death is caused by the inhalation of the toxic smoke. What we need is air to go to a driver for 45 seconds. I'm surprised that this is not done, and I would make it compulsory.
