The headrests are one of the strangest design decisions in my opinion. They jut forward into your head and are extremely narrow. I think they would be especially annoying for a front seat passenger who wanted to recline and take a nap to balance their head on that 6 inch wide section. I read a post by one potential buyer (not sure if it was on this forum or on facebook) who said the headrests were an absolute deal breaker for him, and he literally decided not to buy the car because he found them so uncomfortable. I don't think they're that bad, but it definitely seems like they are another example of tesla choosing form over function.
