Yes, I did get a ticket. It was a 71 on 55 mph freeway. Because that
extra 1 mph is so painfull I would like to know how reliable it is.
Somewhere in the ticket it is written "Speeding. K-15". So I assume
it was a K-band gunn. Because these devices actually compare the speed
of the car with the speed of light, it would imply an accuracy of
1 part in a billion to be able to measure that extra 1 mph. Because
of temperature, and humidity effects I would doubt such a reading (it
was made in Honolulu). Anyone with advice? References? Should I contend
this ticket? Thanks,
			- Fernando
