My comments about judged competitions not being sports were, more than anything, just lighthearted little jabs at something I don't particularly like. Gymnastics, judo, diving, etc., are all primarily physical activities, thus they're sports.
But, none of that changes the fact that motor racing is not.
Concerning judo, judge also have to evaluate technic effectiveness - result, speed & 'involvment' to keep it simple. But let's back to the subject then.
IMHO, you have your very own definition of what a sport competition is: "contest of physical prowess".
But if you look where it comes from...
"Sport" comes from the Old French "desport" meaning "leisure"
In fact the exact definition is "physical or mental pleasure". And when the word was included in english language, it became "sport" and the mental part was kicked out and are now called "game" (chess, etc).
The modern admitted definition of sport is activity governed by rules which implies
physical qualities such as: strength, stamina, coordination, suppleness, dexterity.
If we follow this definition, motor racing is clearly a sport as you need at least stamina, coordination and dexterity.
As far as I am concerned, I must say that I am not agree with that definition because it implies that "electronic sport" are true sports. e.g. Starcraft needs a lot of coordination and dexterity... (miss-clic

)
As you, I think that sport must be "physical". By doing it, you must get or maintain a good physical condition, which is obviously not the cause with video game... Otherwise we would know it!
On the contrary of you, I don't think that having the best build (in strength or stamina) is the purpose of sport. It could be. Like in weight lifting or marathon or let's be extreme, iron man... But it is not a mandatory goal.
This is why I think motor sports are sports: you cannot do it in a medium / high level without a good physical condition. You bring the Tony Stewart example: maybe you don't think so but he has a good physical condition, even if he has obviously some fat. He's not as fit as Schumacher for example but I think that he is way capable of running 20km without any difficulty and a few people on earth are physically capable of running 500 or 600 miles a day, 36 times per annum.
And it is also why I think that it is not a problem that men and women can compete again each other on equal terms - which also implied when gender specific physical differences does not provide a clear advantage - on an activity considered as a sport.
