(Sorry for my English if it's bad) I sometimes crash into a guardrail and it doesn't stop my car, it pulls the car down the hill into a forest or somewhere else. But still very good place for my slow Polonez Caro 1.4 16V.
amazing update, definitely within the most narrow tracks in AC still fun to drive, no weird issues, it has the tightest hairpins of all track! :D https://youtu.be/Jh4lclFEAec
