So after waiting for month I finally got TACC and Autosteer working. I find TACC being pretty good, with exception it seems to me it accelerates and brakes excessively hard in slow or stop and go traffic. As far as Autosteer, I find it pretty shaky so far. It seem my car has a tendency to constantly apply left/right steering corrections, like it is searching for the lane borders, instead of just keeping straight line, even at low speed and on the straight sections of the road. The movements are small, but noticeable - I can feel steering wheel movements most all the time. Anyone else care to share their impressions?
