The game doesn't draw the entire car, it draws the section that you are looking at. If you're looking at a car from one side, the other side of the car has no impact on performance since it doesn't exist. Also, you have to factor in that the further away a car is, the less polygon is actually has since the polygon count can be dynamically reduced. |
That's not exactly the case. Culling poly's (or anything else) can be expensive and splitting that car up and checking what can and can't be seen every frame like that on every car on the road would get pretty expensive and I'm not sure how much that would give you back.
I'm not saying that can't be the case, I'm just saying in every engine I've ever worked in that's not the case. The closest thing you'd have is something like Radiant (or Quake 4 Radiant at least) where they just draw your hands and nothing else. In something like Half-Life 2 with the Source engine you don't even actually have a player model.
