Should be karting, imho. Amateur level stuff.

Karting and indoor trials... that would work.

id have the race of champions style format....no cheeting or difference in cars them

Obviously. Just a slight mis-type there

Don't they use small motorcycles in some of the velodrome events?

if anyone complains it not athletic enough, I'll stick them in my tuscan for an hour at mallory and see if they have enough strength left afterwards to climb out

As much as I like motorsport there are loads of non-motorsport events that deserve to be in the olympics before motorsport.

I wouldn't disagree with that either, but they shouldn't be replaced with motorsport.

My own personal opinion is that the Olympics should be predominantly about sports where human physical ability is the primary thing being tested. Obviously there are existing Olympic events that utilise equipment but with the possible exception of equestrian (which is one I would get rid of) the human is still the source of power. I’ve no doubt that racing a car, motorbike or other vehicle is both physically demanding and skilful but any such racing is critically dependent on a non-human powered engine of some sort. The human factor is fundamentally different with motorsport.

The modern Olympics are also meant to be a spiritual successor to the original Olympics, the ancient Greeks did many impressive things but inventing the internal combustion engine was not one of them. I’d also question the ability of many nations, other than the rich ones, to be able to be competitive within an Olympic motorsport event. One of the few remaining beauties of the Olympics is the ability of a small nation to win a world title.

Finally, the people behind the Olympics are not the sort of people I’d want behind motorsport. I’ve no proof but can’t help thinking that Olympic organisation is inherently corrupt.

But how many complete categories of sport are currently completely unrepresented?

As it happens I'm bind of ambivalent about the idea in general but I think you could make a pretty good case for motorcycle trials (traditional, arena, or both) or Freestyle Moto-X, both of which require tremendous amounts of traditional athleticism, skill, and bravery - quite closely analogous to equestrianism and they'd fit into the Olympics pretty well in my view...
