And while the Williams-Renault team might spend millions every year on designing the correct shape of a wheel nut, motor sport is remarkably easy to start, even for the dedicated couch potato bred on the manic moments of Murray Walker.
If you thought you needed famous parents, you would be wrong. "You can do it with no background whatsoever," says Colin Wilson of the RAC Motor Sports Association, the governing body for all four-wheeled sport in the UK. "Just because Damon Hill is the son of a famous father does not mean it is normal or obligatory. It is not necessarily even a help."
The best advice is to start young - and that means eight and upwards - but even bus-pass holders can try.
"If you are talking about getting to the top, then you do need to start early," Wilson says. "You can start as soon as you have a road traffic licence and carry on for as long as you want.
"There is organised karting for drivers as young as eight. A lot of the top drivers made a name for themselves in karting. It does help to have a track record.
"Everyone thinks they are the world's best driver," Wilson adds. "It looks easy and the pay is attractive, but there are hundreds chasing each drive."
Even money, or at least large amounts of it, is not obligatory, according to Wilson. "In any sport, money is needed. You cannot play golf without a set of clubs, even if you are brilliant. If you like it, you will have to buy some.
"Motor sport is not really any different. What is different is that it is a car we are talking about. But there are plenty of second-hand ones and some parts of the sport are intentionally severely limited to make sure people can afford it."
Auto tests and trials are the cheapest forms. Both use standard road cars but demand a lot of driving ability. In auto tests, the driver must negotiate a set route around obstacles, while trials are not even against the clock. The competitive element is the ability to climb sections of varying difficulty and gradient. "These are entry-level parts of the sport and very cheap," Wilson says. "In auto tests, the good drivers always win, even in inferior cars, and in trials people are still using Hillman Imps."
Racing in a single seater car on a track like Silverstone, which is probably the most popular idea of motor racing, is more expensive.
A special car, different tyres, safety equipment and a separate licence are all necessary. But even then Wilson has a solution. "It is much cheaper to do it at a racing school," he says. "A day costs a few hundred pounds. It is a good idea to try it, to see if you like it.
"You get to drive someone else's car. You know the car will be right and if you are six seconds off the pace, it is because you have no ability. I tried it and saved myself thousands. I know I have no aptitude."
