I notice PWM all around me all the time. Lots of cheaper LED lights use it, and I see it whenever I move my eyes, also when not consciously looking for it - instead of a blur I see series of lamps as a brief afterimage.
As a child I got headaches from CRT monitors at 60hz and I could see them flicker. I haven't noticed the PWM on modern monitors, but maybe these Apple ones would trigger me?
Chevy/Cadillac tail lights? Hate them. Looks like 60Hz, no idea why such a low frequency in a car.

I haven't taken notice of the brand, but I certainly have also noticed a few cars with horrible PWM. It really does look bad I think.
I miss how amusement parks looked at night when I was a kid, all bathed in warm, colorful glowing lights. They are still bathed in warm colorful lights, but half of them now have shitty PWM.

Why should battery-powered diodes flicker anyway?
