Speed

Street signs are funny.  I always see the one that says "Speed enforced from aircraft."  Yeah I doubt it.  Speed monitored from aircraft, perhaps... but unless they’re launching missiles at speeding cars, they aren’t enforcing speed from aircraft.

Then in New Jersey the other day I saw "Speed radar controlled."  Riiight.  So they’re actually using radar to change the speed at which cars are moving??  Amazing.  I didn’t know that my car’s accelerator was adjustable via police radar.
