>>2640424I don't think so. I think you may still be thinking about it wrong. there isn't really a "perfect distance" for anything. It's subjective, and completely up to you. But if you want, post a couple of scenarios and I can try to talk you through it a little more to help you get a good grasp of it.
Basically, if you want a subject to pop, and look large standing out from the frame, you'll want to be closer to it. (like the cars on the track you're talking about. The photographers up close get more "pop" in their images because they're using perspective distortion to make the subject car stand out from the smaller looking stuff in the background)
