True some can’t adjust the angle, but obviously none of them protrude the ridiculous amount shown in the post.
I’m not sure how this isn’t a joke, clearly it’s a riff on how headrests can be weirdly uncomfortable at times. Anyways, if you’re chilling with your head against that the whole time you’re driving you’re not doing it right.
Idk I think because of how much force needs to be contained by the restraint it is rigid for a reason. My guess is there is an engineering reason based on physics.
Also you don’t want people to be falling asleep while driving (anymore than already happens) so maybe that’s a factor too? Like it’s not meant to be a pillow lol
