Only power operated mirrors would be affected. Other systems have trees and
shrubbery intruding into the loading gauge. BUT their mirrors are fixed, and
require a certain "oomph" to move them. Power operated mirros (by their very
nature) would be somewhat easier to move, and therefore more prone to
movement and breakage by shrubbery.

Where else in the world are their retracting drivers mirrors? If you can
find a system that uses them, then I agree, we should use thier system. BUT,
you cannot criticise this point of Craig, purely on the basis that (AFAIK) I
has never been done before.

All systems in the world are unique. EVERY system has unique operational
requirements and capabilities. The vast majority of systems will be able to
apply solutions already used in other systems. Some will not.
