Am I the only one who cannot understand why the headrest is not adjustable manually on the front seats? At my height I have to push the seat back so far I can barely reach the steering wheel so that the headrest glides up to a point it does not dig into my back. In my ideal driving position the headrest is about 3" too low. Surely the ergonomic experts at Tesla understand that people have significant variations in leg length versus torso height and just because you are 6' does not mean that you have the same back height as all other 6 footers. I guess I must just have abnormally short legs since I do not fit the template they have programmed into the position settings.
