Come to think of it, that's a valid point. The damage system in GT5 could blow LFS's away!
I'm not not convinced about this whole "levelling up unlocks damage". I'm not saying that isn't how it is, but it seems awfully strange. Especially the fact that nowhere in the game does it tell you about it!
I'm only level 14 - I find this GT a lot more difficult than the others, the AI are pretty good, and there is usually one which is a lot quicker than the others out in front, which makes it even more challenging
