I am new to Model S and this forum. I have had my car about a week and have been using autopilot almost everyday. I have seen many of the little nuances mentioned in several posts. My biggest issue that I have not really seen anyone else talk about is the fact that it does not recognize cars in adjacent lanes (right or left) until they are about 30 feet in front of me. So, if a car is only a few feet up to about 30 feet in front of me in an adjacent lane and they make a lane change to my lane, the car does not see them until they are almost completely in my lane. I'm almost thinking I have a hardware problem on my car for this to occur. Has anyone else experienced this?
