(Since side mirrors seems to be one of the main topics...) Although heated and electrically adjustable mirrors with signal indicators (and mirrors that fold away when parked) would be a nice government mandated feature, I think the first thing they should do is make properly adjusted side mirrors part of the driving test. What is the point of adjustable mirrors when most every driver has them adjusted incorrectly? (Mind you I have a feeling most driving instructors don't know how to adjust the mirrors correctly).
The Society of Automotive Engineers (SAE) published a paper in 1995 suggesting how outside mirrors could be adjusted to eliminate blind spots. Google it and you'll find many sites with graphics, videos etc demonstrating the correct alignment.
Similar to the experience of first wearing progressive lenses in eye glasses, it can be difficult to get used to the positioning of the mirrors but once you do, you'll never go back to the old way of seeing the side of your vehicle in the side mirror and basically just replicating your rear view mirror.
