15 over on the 219 in one of the 55 zones will get you pulled over every time. That highway is a major revenue source.
That being said, just plead not guilty, go to court, it will get reduced. Everyone knows it’s just a tax system, and the local courts would rather see that tax money go to the town than the state. 100% of parking ticket money goes to the town, while only about 30% of a speeding ticket is kept.
And yes, it’s a known fact GTI speedometers register high. Germany has VERY strict laws about speedometers and car manufactures can get huge fines if one of their cars is ever found to be registering low. So, to take into account for the fact that tires get smaller as they wear they have to make the speedometers read high, especially when a car is new and has full tread depth.
