This bothers me so much. I know the idea is that if I get rear-ended it would help prevent whiplash. But it feels so uncomfortable that I tilt the seat back. This defeats the point of the headrest and I am sure other saftey features. But if I didn't I would be constantly annoyed and distracted. That would increase my odds of getting into a forward facing accident.

Pressing brake:

Make it slow.

Take them all the way out, and flirt it around.

Or see if it moves

Either it is not set right or your head is too long.

Ask Will Toledo.

They shouldn't be uncomfortable. Make sure you've set them correctly.

I always lower the back of the seat as much as possible and raise the front as much as possible so I'm planted in the seat. I can pick up both get without sliding out of the seat. Then I recline a little bit so I can rest my head comfortably. I have seen those more modern headrests that seem to stick way out from the seat. Not sure who those are for.

Just tilt the seat back a bit more?

I am in this picture.

(really need to work on my posture.)

My mom used to have a car like this. I would remove the head rest every time I had to ride in it.
