In the 1990s, our highway police (so-called white mice) had a special VW bus that they used to arrest speeders. A specialist company from Friedrichsdorf had converted it so that it was not recognizable as a racing car. Many sports car driver lost their composure when they were stopped by this bus. I had a 2.5V6 Steinmetz at the time and thought I was standing still when they drove past me (not as a speeder). Laughs
