From today I am no longer a racing driver. I'm retired and I am very happy.

I would have been a much more popular Wolrd Champion if I had always said what people wanted to hear. I might have been dead, but definitely more popular.

Sometimes you need to ease off in order to go faster

There has been a huge advance in technology, which has improved the safety of the cars incredibly, but there are still some heavy crash impacts and in certain circumstances there is still the chance of fire today.

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.

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.

For a quick lap at the Nrburgring, you've probably experienced more in seven minutes...than most people have experienced in all their life in the way of fear, in the way of tension, in the way of animosity towards machinery and to a racetrack.
