Many of not most newer cars feature an engine cut off feature when stopped at a red light etc... where the engine stops running as long as you foot remains on the brake with the car in drive. In fact my wife's Ford Escape has this feature. Obviously no reason to use gas sitting still.
My question (seeking opinions of some mechanics here) is this. All my life (I'm 64) I've been told "the hardest thing you ever do to an engine is start it"... as most damage purportedly occurs when you first start an engine - due to lack of lubrication in various areas.
This begs the question, is the auto-stop feature actually shortening the life of the engine due to it's frequent start/stops, or has this been taken into consideration in the design?
