I remember reading in the past that people had issues with the car slowing down significantly when there was a car on the shoulder and some even reported the car getting confused with overhead structures and overhead road signs and slowing. A few times today on the way home using TACC and AutoSteer (when traffic was slow enough) my car would hit the brakes when going under road signs. At one point a very scary beeping sound came on and the car braked extremely hard and I had to punch the accelerator so I wouldn't get rear-ended (I was using TACC at this point). I know with AP2 this is all still early and in beta, but is anyone else experiencing this when going under highway road signs?
