Why is there damage in Forza but not GT?

[Zkuq]

Who cares if there's a damage system in GT5 anyway? It's not like it really mattered in a game where you are supposed to NOT destroy your vehicle, and if you happened to do something that would cause damage, some other solution could be found (most likely slowing down the vehicle, a lot). Gameplay-wise it wouldn't be worth much, immersion-wise it would probably help quite a bit.
