I moved from a Lincoln MKX to my Model S and one of the first things I noticed was when backing out of my drive the Model S doesn't warn me of approaching vehicles coming in either direction down the road. The Lincoln MKX would warn me of cars roughly 200' away coming at me. Yes I always look so I am not depending solely on this feature. As one of the most sophisticated cars on the market this seems like a must have, right? Could I just not have a setting turned on? Is there a setting for this? Thanks for your time.
