So you think it is, don't push Off  . . . and leave the car.

Which starts running again a few minutes after you left.

This can – and is – happening because of Automated StartStop (ASS) the new "feature" many new cars come standard with as a fuel-saving measure. Whenever the car stops, so does the engine – the idea being that a non-running engine doesn't burn any gas or emit any gas. The gains – and reductions – are almost immeasurably small per car but necessary from the standpoint of regulatory compliance – the fuel economy and emissions fatwas that are becoming otherwise impossible to comply with – without switching over to electric cars, which is another story.

So ASS automatically turns the engine off whenever the car isn't moving, as at a red light or when traffic stops moving. When the driver takes his foot off the brake and depresses the gas pedal, the engine automatically restarts itself and the car resumes moving.
