<VV> Radar/LIDAR & Front Plates <-- Correct-o-mundo

[Charlie]

Actually, I left out some details re the radar/LIDAR distinctions, to
simplify my plight:

To quote the article I read (Word 2007 docx attached) :
"This small beam width has another added benefit - it cannot be detected
until after a speed measurement is already made. Testing of the most
advanced detectors has shown that when officers aim properly (at the
vehicle's front license plate instead of the windshield where the detector
usually sits), the signal often goes undetected."

When I got stopped, I alluded to the cop that he "got the wrong car" and so
he claimed that's not true about LIDAR.

Maybe true, but I managed to prove that he didn't actually have LIDAR, since
his LIDAR unit (as stated on his citation) was in fact out for repair on the
day he claimed he used it on me!  
(He said I that printed the receipt in PhotoShop, and the judge bought it,
ignoring my certified copy.)

His LIDAR unit, as I said in court, "has spent more time in the shop than my
car," at least 4 times since it was "assigned" to him.  Since it was "in the
shop" he used a "leftover radar" unit instead, according to his captain.

Anyway, that's how I learned about license plates being used to trap
speeders (or in my case, innocent "dolphins in their tuna net"?)

And, as you said, the "prominent downward angle on the front of the LM" may
be what saved me from all my "priors" (which is one reason I figured it was
a bargain only getting caught this one time, even if I was innocent.  It's
the Murphy's-based irony, under the cloud of which I live.  Murphy only
leaves my side to visit his joys on others, but he LIVES here;>}~!)

While it will have little to no effect on a radar gun, the front license
plate is the target of choice for police when using a Lidar gun.

With its prominent downward angle on the front of the LM 'vair, I've often
wondered how difficult it would be to get a positive reflection off of it
with a Lidar gun.

Regards,
Joel

What difference does a 12" x 8" or so aluminum plate on front of a mass of
steel about 24" x 55" have on radar reflections?

Extremely minute!
