My late wife got sick and we all hounded her to stop smoking or she would not get well,she stopped smoking and died 2mths later,might as well kept on smoking. Something about how it is impossible to avoid our fate,I don’t know.
I consider Al Gore?s admonition about wasting gas as (part of a) remedy for pollutants in the atmosphere, subsequent climactic changes, and threatening the lives of species living on Earth. Is the cumulative cost of unused gasoline saved by shutting the engine off at traffic / train lights versus the cost of a new starter the real question?
It does appear to be what the OP is asking.
