When driving my right knee is literally an inch below the shift knob. I have this fear of knocking it into reverse if I alter my position while driving. To me the positions of "R" and "D" seem counterintuitive. I've only had my Prius for a week and a half but I invariable put it in reverse when I want to go forward. If "D" were up I wouldn't be as concerned over bumping the knob into reverse position. Does the Prius transmission protect itself from a dangerous shift (ie reverse while at highway speed) like some vehicles or would it alow itself to be destroyed?
