[Christ]

I engine brake down hills, even if the engine is off. (In manuals, not automagics.)

I don't coast more than a few MPH over the speed limit, remaining well within the 85th percentile, which is a rule applied to roads in all parts of this country. Prove that you were within the 85th percentile of motoring speed, and you're off on the ticket anyway. The only speeding tickets I've ever had to pay were for like 93 in a 65, 101 in a 55, 73 in a 35, and 125 in a 25. All of those, I got pleaded down to traffic offenses, because in each case (I took them all to court - never plead guilty.) the cops couldn't remember anything about the particular incident, and thus were found incompetent to defend their position in issuing the citation. For each case, I offered the Judge a deal instead of having to go through further deliberation, and in each case, I got off much lighter than I should have, because the officers don't expect that the driver will actually know the law.
