between measuring time between short distances (approx 0.1 miles usually) and over a long stretch of road. Any speed measurement is some change of distance over some time increment. Monitoring somebodies whole trip and figuring out whether they might have been speeding is harassment (in my jaundiced viewpoint of course...) Then, of course, I don't really think that it is proper in a free society to use the police departments as a profit center either...

Yeah, I know... it's legal...
