2021 White Calligraphy
Well they claim 15% fuel savings so I don't think it's useless. I mean common sense is if your car is off then it's not burning gas.I HATE this useless feature. I'd pay extra to get a hack to turn this thing off permanently. One more stupid design idea in car building!
But there are plenty of hacks if you search the forums. Everywhere from sticking something in the button to jam it down to save you 1.69 seconds from pushing the button upon startup to buying a relatively cheap device and installing it.
