AP2 stil needs to settle down some but the PCH is not a problem except the right lane guard rail south of Will Rogers Beach. Kanan Dume has more room to roam (and AP2 does) but Malibu Canyon is a no go for me without very vigilent, hands-on co piloting essentially disengaging more often than not. The power lines crossing the road cause momentary sudden deceleration, and there is very limited room for error regardless of travel direction.....the cliff or the rock face. TACC adjusts speed pretty well and no problem with either tunnel. Latigo will be the ulltimate AP2 litmus test!
These are not 90mph roads, but I'm sure you know that.
