Another addition was made to keep the Autobahn circuits some of the safest in the industry. Additional guardrail was installed on the right of turn three on the south track. Since the opening of Autobahn the length of this guardrail appeared sufficient and then in a short period of time we had three different instances when a car got past the rail and into the back side of the barrier along the front straight. The addition of 25 ft of new rail has been installed to eliminate this possibility.
