They are vestigal in humans.
They are tied to fear responses in animals and in humans. But in humans they serve no purpose since they no longer are tied to standing hair on its end to increase size. Same with the response to cold.
Vestigal means that a structure has lost its ancestral function. The Coccyx is vestigal in human since we no longer have a tail however it is still the anchor for some muscles around the pelvis.
You have to use the word it is defined by biology not as you wish it to be defined.
