Regarding the reflection of laser light - unless your car has a true mirror
finish, the light tends to be reflected in many directions by irregularities
in the surface.  Therefore it is theoretically possible for a detector to
pick up a reflection from even an oblique surface.  Battlefield 'smart' 
weapons work this way.  However, they typically operate with a fairly
bright laser, whereas a police laser would need to be toned down drastically
to meet safety requirements.  This may make it difficult to pick up and
separate a reflected signal from background light, particularly if the 
car does not reflect very well.  Also, in keeping with government standard
operating procedure, these lasers will be manufactured by the same high
tech outfit that sold 'em all the original radar detectors.  We'll also 
know what frequency they lase at, and it might be fun to shine the same
color light back at them as you pass by.
