The externalized consequences of drivetrains failing faster (or being abandoned because they give the perception they might) easily offsets whatever gains are achieved with this nanny tech.
Auto start/stop is a great example of weirdly aggressive nerds failing to explore nuance, which is found everywhere.
I feel these kinds tech are more symbolic than functional and exist to simply check off boxes to obtain environmental ratings. I would even guess the environmental ratings are also short sighted and exist as symbolic gestures of environmentalism. Basically, environmentalism performance theater.
That's a matter of opinion, which may not be shared by anyone living near places that have seen decreases in noise and air pollution due to idle stop.
It's "idle start/stop". not "idle stop". At some point the light will turn green.
