Race driving is definitely a sport - I don't do it myself, but I have friends who do, and you really need intense concentration, superb reflexes, and excellent fine motor control.
Why couldn't they do that with dive skills? They can do it with gymnastics or figure skating...! Probably not such a great idea though, don't know how many true fans there would be out there to support the games...
Yes of course race car driving is a sport--I didn't say it wasn't. It is competitive and there is a winner, as well as the physical aspects. So as I said, according to my definitions, regular driving on the street then would also be a sport. Because that is the case with just swimming laps for fun being a sport because swimming is a competitive, record keeping activity. Same with bicycling. But, these two are recognized -- and televised as well-- when there are competitions (like Olympics, Worlds, Tour de France, etc.) Regular driving is not, so it is an exception to my rule. Golf is a sport because it is competitive, either against yourself or others)--and is recognized by a majority of people as a competitive activity. Thus it is also televised. Mountain climbing, skydiving and hang gliding are generally considered sports, but not according to my definitions. These can have extreme physical aspects. But they are rarely televised, and hardly talked about unless you do them and talk to others that do them.
"Sport Fishing"--No. No at all USUALLY physical enough (yes it can be hard to fight a hooked 45 inch Pike for 20 minutes), and no competition, except for special tournaments--that no one hears of unless you fish. Hunting--Not. No competition--yes skill, but physical most likely when you have to drag the Moose to the car.
To respond to another post, things like chess--no. Nothing physical even though competitive. This is a Game.
Baseball is a Sport, and Activity and a Game. Some things are all 3. Some 2, some 1.
Billiards--Yeah maybe. Borderline--not much general interest, TV coverage, etc.
Ping Pong-Sport.
Figure Skating--yes sport. Judges grade on specific techniques and overall presentation. It is competitive, very physical-- and well known. Scuba skills.............You could grade on who's got the most perfect buoyancy and who can flip around doing tricks best in an aquarium. What else? Nowhere near cuts it for me as a sport.
Now, the difference between Sport and Sporting............
