I am always curious how the Germans and other Eurpoeans have the Autobahns on which to drive as fast as they wish, seemingly very disciplined and well controlled. How fast does the average driver cruise on one of these roadways. More importantly, how fast could I comfortably and safely cruise in my 420SEL on these roads. I guess my real question is how does Mercedes engineer this kind of capable speed into their cars, when say a Ford Crown Victoria( I own a Ford too) seems skiddish and hard to control at very high speeds. Curious for your feedback...
