Just got the update and drove on the freeway a bit. Full speed auto steer (80mph.) Lane change with the blinker is interesting. Works pretty well, but once it hits the middle of the lane dividing line it kind of jerks into the lane. It definitely will not change lanes if it does not see a lane (which it shows now) or if the lane has a car in it that is to close. No change in speed for local roads, still 35mph max.
I did not need any calibrating, worked right away. Noticed some places where it would get confused that it does not anymore. Noticed it almost 100% of the time when there was a double yellow island where the road is flat, no curb, but they use cross hatched yellow lines between double yellows to designate where you shouldn't drive. Before this update my car would always dive into those islands in an almost aggressive way. It was always perplexing because the lines were very clearly painted. Now it clearly sees the lane and does not get drawn into the pseudo island.
