Some of you guys still don't get it. If you get clocked doing 65MPH it don't matter about a head wind or a conveyor belt etc. Your still doing 65. I don't care if you have a V12 and the peddle is to the floor, if your doing 65 then your doing 65. Same for a boat, GPS and radar don't give a rats azz what the current of the water is, it has no bearing on how fast the vehicle is moving over the face of the earth.
I understand what you guys are saying but it plays no part when being shot with a radar or using GPS for speed. The way you guys are rationalizing this, you would need to take into account the rotation of the earth too.
You guys are probably teachers and now we know why kids graduate HS and cannot read or write. You probably buy into the Commie math too.
