Exactly. And controlling a very high powered car (or feckin' huge horse) also requires controlled physical motion, strength and technical control.
So by your definition, a driver or jockey, must also be an athlete.
If sport is something in which human athletes compete, then motor racing and horse racing are sports. (Darts too for that matter!).
I get that the gripe with F1 is that the best cars win, but they don't always win. The driver is a factor too. Similarly with horse racing.
I think that's why many (most?) people, consider them sports, and also why bookies make money on horses!
Anyway, I'm not here to wind you up mate. I've enjoyed the debate and we've not yet resorted to calling each other names, though I've probably been less than polite sometimes, sorry. If we disagree, it's pretty trivial stuff in the scheme of things.
The one thing I'm sure we can all agree on is that darts simply has to be in the Olympics.
