Car idle damage?

[C.A.R.]

Car manufactures wouldnt/couldnt release an engine that would damage itself while left idling, what about if you were stuck in a traffic jam.

Pressumably you would have to drive to that traffic jam so had put load on the engine already, pumping nice juicy oil all over the moving parts in the engine head where it is needed.

Unless you wake up with your car already parked in a traffic jam...which would be clever.
