Fahren Fahren Fahren auf der Autobahn

I drove on the autobahn yesterday and found it both exhilarating and nerve-wracking.

If you are in the fast lane (no speed limit) you'd best get out of the way when a Mercedes Benz sedan hurtling along at 140 or 150 KPH comes up behind you and flashes lights.

I got up to 157 at one point, but did not like going that fast, kept to speeds around 120 to 130.
How can there be no speed limit? It boggles the mind.

Mark drove today and despite our speeds of 130-140 KPH cars were speeding past us in the left lane like a blur. They would whoosh past, shaking our not tiny SUV, must have been going 160 plus!

P.S. If you do not know the 1975 pre-techno classic by Kraftwerk called "Autobahn", check if out on youtube. At the time the group dubbed this new musical style "machine music".
