[Mgs] "black plate cars"

[Stephen West-fisher]

How would that work? Both light and RF travel pretty much at the speed of
light. I would think the very minute delay in creating the proper Doppler
shift and transmitting it would cause the original signal to get to the
camera just before the "doctored" one. Is there any documentation of such a
device working?

There is also a transponder available 
which when it gets a 'hit' from a laser speed detector sends a signal back 
at a much higher velocity and preventing it from recording the vehicle 
speed.
