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.

Juan Fangio was the great man of racing, whilst Stirling Moss was the epitome of a racing driver.

Sometimes you need to ease off in order to go faster

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.

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.

It takes leadership to improve safety.
