I genuinely wish everyone involved in thinking of, pushing and implementing idle-stopping was forced to use it and pay for the engine replacement it will require.

Everyone I speak to hates it. The shit they do for a 2% mpg gain is embarrassing. You can't even turn it off. At least on Honda and VWs, the button exists but it turns back on when you restart the car. You have to click it every single time. I genuinely wish nothing but the worst for anyone working on car software for (almost) any brand because they are all shit and designed to infuriate the user.
