And where did this "gem" come from? Smells like cow doo doo, if you ask me.
First things first, the police cars don't "flash" - they use video on board and calibrate this with timings over a mile. If they are stationary radar traps at the side of the road, they would use flashes but then any good lawyer could claim it was one and the same offence, especially as within a few miles of each other we can reasonably expect the speed limits to remain fairly constant and not swing up and down.
Secondly, if I drive through a speed trap at 123km/h where 110km/h is allowed, don't see the flash, get caught by the second one, I really would like to see the judge who would take my licence away. 13 km/h is sufficient to trigger the flash from a stationary camera but exceeding the limit twice by 13km/h would not warrant a statutory ban.
Under German law, you can only take the licence away from someone if they:
- break the limit on the motorway by more than 26km/h within a period of 12 months. Being flashed twice within a few miles would be considered one offence
- exceed the speed limit on the motorway by more than 40km/h.
Thirdly, the MAXIMUM imposable fine for speeding on the motorway is €600 for driving more than 70km/h..... Even if it were considered to be two offences, this would only be 1200€.
