Most people rightly don't make such a fuss because most people just want an easy life.
I think that may be an issue. If they use a speed gun, how do they prove that they were not moving?? It is all so subjective.
Imagine they are in two knots of current going with the current at one knot, that is three over the ground.
You are doing five knots over the ground upstream, one knot under a six knot limit!
They would read your speed at eight knots!
Explain that in a court of law!
