I don't have any problem with it, but my wife is having a lot of trouble driving our new getz with the head rest in place.
She is reasobnably short and finds the headrest very uncomfortable, in fact makes her feel ill after a while. it pushes her head forward from a natural position. She has driven many cars in the past and has never had this problem.
Probably not a good idea to drive without it, thought of buying another headrest and bending the arms so it is not as far forward. Any suggestions, or anyone else have this problem?
