Rush Limbaugh's law on sexual harassment: She will either
1) sue you, or
2) hit you, or
3) marry you
And I might add, if she marries you and you STOP harassing her,
you will die a slow, protracted, NOISY death.

everytime I run through a toll plaza where the cameras are equipped with
IR Illuminators to light up the plates at night.
One explanation I read was frequencies of the mobile units, since they
aren't used for enforcement, per se, are not calibrated/recalibrated and
the detectors won't pick them up.
No attribution was provided with that explanation so I rather doubt it
for that and several other reasons.
A lot of drivers don't stay at the same speed, they're impatient and/or stupid and speed up, then brake as they approach the car in front. That's why you get those ridiculous rolling slow bits on motorways sometimes. I always delete them by just driving at the average speed of the cars in front.
Mary had a little lamb, it walked into a pylon. 10,000 volts went up its arse, and turned its wool to nylon.
That makes sense....
I have also noted that those signs are always showing about 2mph slower
than my speedometer on my pickup truck. But vehicle speedos are never
100% accurate because of factors in the vehicle, gear ratios and so on,
but tire size is a huge factor. I have heard of guys changing the speedo
gear, just because they put on larger or smaller tires. As long as I
know that my speedo is showing "30" when I'm actually doing 28, I know I
can legally go a little faster. I actually like those signs, because
they do "test my speedometer.
I dont know what size tires came with my truck, but I tend to run
heavier tires than most people, because I haul farm equipment, hay
bales, etc. I'm sure that makes up the difference. My tires are all
10ply, and the quarter or half inch of extra thickness does matter in
the long run.
A negative speed? Huh? NO It's doesn't care what direction you are going.
The beam pattern is narrowed so it's only measuring the oncoming traffic.
The ones we have recorders are installed so traffic studies can be
performed. When citizens complain about speeding in their neighborhood then
a study is done. If warranted then enforcement is started. Usually the
studies are done in nearby areas too. Catches the complainers speeding in
someone else's neighborhood. Enforcement catches the stop sign violators.
The physics cares. A car appraoching at 35 is very different from a
car going the other way. The software might be programmed to display
the absolute value of the speed, but internally, the device knows
toward (positive) from away (negative).
That may be the intent, but real world roads have curves and cars on
the other side are sometimes detected.
So. They are not being used for enforcement. To be used properly they just
aren't hung on a fence nail in the pole. Are you looking in the mirror when
you pass one going the "negative" direction; if so what is the reading?
