Theoretically, wouldn’t the excessive frequency of cycling the engine off and on also cause excessive and premature strain and wear and tear and shorten the life of the Engine Starter Motor? Any money saved on gas would eventually be spent on buying and installing a new starter perhaps sooner because of the extra work it has to do. And as far as the environment is concerned, the manufacture of more new starters would also require use of additional natural resources and energy. I’m just armchair speculating (which I’m prone to do when I’m not armchair philosophizing). What say you?

I had originally thought the same thing, but have since learned (from talking to GM engineers) that today’s vehicles with start/stop come with “beefed up” starters, batteries, and wiring. So, yes, the additional starting does put a strain on components, but those parts are heavy duty by comparison to parts on a non start/stop vehicle, so the net result is they will last just as long since they were engineered to handle the additional demands place upon them.
