<VV> Radar & Front Plates i.e. : "vertical reflecting surfaces"

[Frank DuVal]

As I said, very small effect. Not enough to get out of a ticket.

So, if you were several miles away on the desert, maybe, but I still 
doubt it.

If the license plate theory was actually true, how do radar guns work in 
states without front plates get the job done? They sell the same guns there.

All it takes is a small reflective signal for the radar gun to receive it.

I also find it interesting that people in flat states think the radar 
signal needs to reflect perfectly off a vertical surface for the system 
to work. We use radar guns here in the mountains where line of sight 
does not mean straight onto a flat vertical surface. The signal reflects 
off most of the metal in the car. Even from metal behind the plastic 
bumper, fender, and hood (think Corvette for a whole car example).

And it will be interesting what you say to the police when they stop you 
for not displaying a front plate. If they find you "interesting" they 
will use that as an excuse to stop you.
