lol, glad you know what billions of ppl on this planet need/dont need, when sitting down.
you do realize not everyone has the same height/shape/weight, just to name a few things why ppl might like having one.
and no, you dont use headrests for "racing", unless in road legal cars, adjustable to get close to the head while driving,
to prevent whiplash/injuries when getting in a crash, NOT to rest your head, unless you sleep in your car.
they interfere with the SAFETY HELMET, and the main reason proper racing seats are bucket type with u-shaped support. and as you can see, neither adjustable, nor pillow like.
racing seat, while
this is used to keep your head fixed, not a head rest.
these are made by "5" plants in asia (and sold by hundreds of brands), for large countries with smaller population, then put online to have a cheap moneymaker.
anyone taller than 6ft/190cm will have a hard time enjoying it, no matter brand or what support/pillows it has,
as none were made for taller folks.
