In one of Clarkson's books he whinges about how race drivers hate road cars because they're slow and they understeer.
He goes on to talk about the BMW Diesel challenge they did (where the four TG presenters raced at Silverstone National).
Despite being a 100,000 mile ex-rep-mobile their BMW (fitted with race slicks, race suspension and a few power mods) astonished Clarkson... he wrote that he kept coming to a complete stop every time he touched the brakes
Suddenly he realised why race drivers only actually like race cars.
I may be rambling - but hopefully you can see the point!
