12.3.6 may be a point release for parking, but it's messed up other behaviors for me. After weeks of disengagement-free drives, today's trip left me puzzled. On leaving my house, there are three intersections without either stop or yield signs. In the past, FSD would pause, creep a bit and turn. Today at every one of these intersections, it stopped and sat until I poked the accelerator.
Also, FSD failed to properly traverse a two lane roundabout, stopping well before the circle and then stopping in the roundabout for no reason. Again, previous versions had handled this roundabout with ease.
