I'm not a designer but one principle I've adopted in most things I purchase is to minimize complexity. My goal is always to optimize for "least willpower consumed". Because I know that if its not easy to do, I'll just skip it after a long day. If I was making something for professionals who might use the tool for long, tiring hours, I'd probably want to give them the least bit of complexity possible. At the end of an 8 hour shift, how many truckers will have the energy (or rather, spare willpower) to press a button, wait for the mirrors to retract, clean it, and press the button to get it back into its original position? Compare that to the much simpler single-step current process (grab cloth, clean mirror). The fewer clicks, the fewer steps, the fewer movements something takes, usually, the better.
