On mirror vibration, my personal experience is that a lot of it is contributed by the diesel engine, at least on the freeway / at idle. It is really obvious when you're cranking it. The proximity of their mounting point to the engine bay doesn't help either. IMHO the axle-mounted motors are gonna suffer less from this particular cause, but maybe the bad roads will make it worse regardless. A related point is "E-mirrors". The regulation is not there yet in the U.S., but apparently they are in Europe [1]. I think they have the potential to be _more_ safe than traditional ones, despite the glare issue at night --- for example taking advantage of the low-light HDR capabilities. Also, their FoV don't shift around as the driver's head does; this may be both a pro and a con.

Also, had they made the driver's seat slideable left-to-right (e.g. with 3 locking positions) it would solve the problem of not being able to hand something over the left window ;)
