There was (and still is) a good reason why the left-right "chicane" at Adenauer Forst attracts so many spectators on a day with tourist drives: too many of the drivers overestimate the speed that the left turn allows and need to go across the curbs.
obviously you can not really estimate the left, as in the approach you are too deep to oversee this part, but the armco, you can still see, is going straight on, so many unexperienced think, the track would follow this line, so they suddenly notice, the curve is much more bent, not following the armcos. Thus they try to avoid to hit the curbs and the dusty safety area with too much steering , which results often in spins , in the early time rollers (hairy crashs you can watch at youtube).
This picture i took in 1968, still no armcos, but the line of the bushes also caused wrong impressions. This section always suffered unclean tarmac as well ,as you can see from the dirt on the track, very slippery during wet conditions.
