If you're a fan of endurance races then you'd want damage as one of the top features, not weather or time transitions. There's nothing endurance about being able to wall grind, bump n run and pinging redline while downshifting. Biggest endurance race in the world is LeMans24 and every year almost half the starting grid goes out due to some damage related event, whether it's a crash or a system failure of some sort.
I wonder what part of that includes the visibility changes as an integral part of races, and the strategy that has to be executed when different amounts of grip are present in the surface as they change depending on the weather, also the part that considers endurance races as more lasting than 2 hours.
However it does lacks the Deux-Ex Machina that gets you back 5 seconds in time, that is uber realistic.
