A minor disagree on that point: I drive my M3 most often in Chill mode, and it doesn't lag or lack power at all; indeed, compared to most ICE cars, it's instant and powerful acceleration. Yes, not having it in Chill Mode is faster, but the difference is not huge, I don't think.That's funny! But it would be disrespectful to the name of one of the most amazing innovators to ever live.
I always thought that "Chill Mode" was probably initially referred to as "ICE Mode" by the Tesla engineers (as it really does replicate the time delay and lack of power typical of ICE cars) but Elon saw that as escalating the anti-EV sentiment and suggested "Chill Mode" as a more hip, less antagonistic alternative.
