I don't think I'd like my car to be completely "black" at IR during
the summer!  Prolly not even during the winter.  It's hot enough reflecting
all the heat it does now...  Rather than absorb the IR laser, I'd rather
jam it by sending my own noise (lots of random heat).

I wonder whether a laser of sufficiently low power to be safe for use
in public really would be useful what with all the background noise it
would have to deal with.  If it's not significantly cheaper than the
hand-held radar units, and may not be more reliably used under expected
conditions, why would a PD buy one?  The small radar guns that are on
only when you're being clocked defeat radar detectors for the most
part, unless your detector hears the traffic in front of you being
clocked, and it takes a pretty smart detector/driver to distinguish
that short signal from the local bank/Burger Thing...
