I genuinely don’t see the problem with those. Amber lights on the left side of the car light up, that can only mean one thing. There is no ambiguity there whether they’re playing snake or just flashing. I have never, on no occasion, found myself confused by those.

This concept isn’t new either. Factories have been using very similar methods to use the heat of the exhaust gasses to power the sensors and whatnot on top of their smoke stacks for some time now, for example.

IIRC that was just a poorly worded statement from a rather unimportant ms employee who really wanted to say “it’s the latest version of Windows”.
