[Bob D'Amato: Re: License Plate]
The other reason for mandatory front license plates is to provide a nice
reflective surface for laser speed measurement -- one of the reasons many
states have adapted light-reflective materials for the plate design.
There are several companies selling clear plastic "radar-absorbing"
license plate covers to neutralize LIDAR (sorry, I don't have any info
on whether they actually work). One nifty trick I've seen here in NJ is
to carefully mask out the characters on the plates, then airbrush the
reflective background with flat automotive paint to match the original
color and pattern (the NJ plates have a boring beige-to-white background
so it's easy to simulate -- could be difficult on fancy "picture" plates).
Peel off the masking tape when done and voila! Instant reduction in LIDAR
I've also seen a couple of things for helping defeat photo-radar. I
once saw an ad for a plastic license plate cover that contained a polar-
izing layer(s) that would obscure the license plate if viewed from more
than 15-20 degrees off-axis. I've also heard that several heavy layers
of high gloss polyurethane on a smooth plate (ie: without raised letters)
will cause reflected light to sufficiently obscure the characters when
photographed from an oblique angle.
Standard non-liability disclaimer applies - I don't advocate or practice
any of the above-mentioned techniques which have been provided for infor-
mational purposes only. YMMV!!!
