As a mechanical/technology geek, this is why f1 will always be top:
However, a bit like the Olympics, i always wish they would have an unregulated, go as fast as possible, using anything available, category.
For purist driver racing, they tried that with the sealed setup and rover 25 cars, nice idea, but so dull to watch.
The electronics side of technology is of little interest to me so, for me, some of the most exciting cars were the old Can Am monsters, McLaren etc. Have you seen the film of his life - simply titled McLaren - I'm not ashamed to admit it had me in tears.
