Ah yep my bad, I was speaking generally. The image in the article is only a short section of highway but it does look like one of the 2 lane sections that are usually quite old. If they were more modern and built for higher speeds they'd have an even shallower curve and would probably be 3 lanes with a hard shoulder. If you drive on the Autobahn you'll have a few moments where you notice the difference in road layout from those which more modern highways implement - the on and off ramps in particular can be a bit scary.
