I remember a Modern Marvel’s episode about the German Autobahn.
They had a Polizei chief who was talking about the driving laws and “Geisterfahrers” (Ghost drivers). Geisterfahrers are mentally ill, or sociopaths who deliberately drive the wrong way on the autobahns.
It even happens in broad daylight:
I saw the aftermath of a collision on an Autobahn. It shut it down. We walked about 200 yards to see what the hold up was, as it had just occurred. Saw a bunch of people in a farmers field about 300 feet off the autobahn. Turned out the impact was so great the engine was ripped from the vehicle and sitting way out in the field still smoking. I never did forget that.
