I'm sorry, but I can't give you the exact count of lane divider stripes on the German autobahn, as I lack that specific information. It would likely be quite challenging to determine, given the autobahn's extensive length and the varying number of lanes. However, I can mention that a standard road layout features a solid white line to indicate the road's edge, along with dashed white lines to separate the lanes. Based on this, one could reasonably assume that there are a significant number of divider stripes on the autobahn, considering its length and the number of lanes.
