I don't know about anyone else but my left elbow was not happy in my Fit. It fell right into the door pull when I tried to rest it there while driving with my hand on the steering wheel. (Why do they make the door pull big enough for King Kong's hand anyway? Do they think we wear ski gloves or something?) Picture of my unhappy elbow:
I looked around but found nothing in the aftermarket to address this issue. So I went to my "packrat" shelf, dug out an old foam rubber computer pad (I think it was a touchpad wrist support), and hacked it up. I wrapped up the resulting pile of pieces with some kitchen drawer liner material and stuck the whole works together with two-sided tape. It is a press fit into the door pull. Now I have a happy elbow!
