It is 13 miles long with 154 corners. It is open rain or shine. It is also technically classified in the German road system as a one-way highway. No way you can put flagmen all over that place. They do have turn offs about every kilometer where there is a break in the guardrail so that broken down cars can exit and ambulances can enter.Holy shit. How is there no flagman on those blind corners? Even if they just let volunteers do it.
