Very interesting. I'm wondering what's the speed limit in that locality. Maybe 55mph? Also, have you unwittingly (which really means stupidly) opened yourself to prosecution and losing your licence by flagrant breach of the law? Obviously, people who are rich enough to blow money on vanity cars, often have a mistaken notion that they are "above the law". In an uncivilised and primitive country, such as USA, you will get shot for displaying this attitude (if you are black, and the cops presume you have stolen the car, which is a given, since black people don't have money or nice cars unless they steal the money and nice cars, in the racist police imagination). Here's hoping you very soon end up in a cell with a black man who's been wrongly convicted for jaywalking or some other capital offence).
We don''t need to be shot and we don't need to go to prison. The speedo in Germany shows km/h and not mph. The speed limit on country roads in Germany is 100 km/h. So everything is okay.
