I used to do it all the time back in the mid-80’s in my Maserati Bi-Turbo with the special 5-valve heads. 300HP in a 2700 pound car.
Great ride.
I thought I was pretty special until one afternoon I was blowing up the Brenner Pass out of Italy towards Austria doing about 140MPH indicated when a Bimmer flashed its light for me to get over and a Teutonic-looking blond couple, of obviously heroic and noble appearance, with a couple of look-alike young teens in the backseat, blew past me.
With a couple of windsurfer boards on a roof rack.
The guy was a stud.
I drove on the autobahn for 4 years, but I was always careful to stay out of the left lane. I saw cars go past me, like I was standing still. From what I could understand, they did not have a lot of injury accidents on the autobahn. The accidents were mostly fatal, due to the high speeds.
Only 140? No wonder you got passed. I got zapped by Benz on about 50 km south of Munich. I was doing 160. The Benz was out of sight in less than 20 seconds.
Sadly, there far fewer unlimited sections on the bahn than there was in the 80s.
I had pretty much the same experience, minus the blond hair and surfboards. I picked up a new BMW 335 convertible at the factory in Munich some years ago. I asked the customer service guy if it was necessary to limit top speed or RPM's while the car was getting broken in, and he openly scoffed at the notion. Apparently they take pride that their fine pieces of German engineering are ready to be pushed to their limits right off the assembly line.
I managed to get the vehicle up to 135 mph (well over 200 kph) on a long straight stretch west of Munich, but I was shocked to be passed by a large Benz going 20 or 30 mph faster.
The Germans have the same relation to unlimited autobahns that we Americans have to our guns.
