>As the saying goes "Not hardly". I do plead guilty to driving like a star, entertaining my wife and having a blast. As I remember the only divided highway in France was about 200m before you got to the border crossing at Saarbrucken where you got on "the autobahn" (there weren't many of them). The only speed limit on the autobahn then that I know of was right in Frankfurt- 150 kph- why bother. All the other roads in France were 2 lanes or 3 lanes with a center, for whoever got in if first, suicide lane. But, I was young and "bullet proof" in those days.

Some speed limits near Frankfurt actually make some sense:

- between Wiesbaden and Frankfurt one of the most dense traffics
- coming down from Taunus (Friedberg / Bad Homburg) some drivers try to stay at speeds going over the western crosses
- coming up from Heidelberg/Mannheim, between Darmstadt and Frankfurt is a high speed stretch coming into Flughafen cross

The stretch between Darmstadt and Frankfurt claimed quite a few deaths from Rosemayer in the 30ies to some high speed test drives with new cars from various makes and was a way to scare the pants off new drivers here, with cars trying to reach 300Km/H at night.
Daytime and fair weather, left lane speeds are usually upwards of 200, so coming to Flughafen cross a reduction is helpful ;-)
Now they will try to electrify one lane, uncertain if speed limit will be added :-((
