I have noticed that AI drivers in a group will stop and do crazy things on the road between Panagia and Chalkeia. The middle vehicle in a group tends to stop and rotate 180 degrees before correcting itself and carrying on. It doesn't happen every time but still happens far too often. It's almost as if the middle vehicle thinks it should turn off on one of the dirt roads that adjoins the main tarmac road, when it only needs to carry on.
