I have an AP1 model S 90D. When driving on the freeway with many cars around I can see them show up on the dash screen. On my s75D WITH AP2.0 I only see cars in my lane in front of me. If the car changes lane but still in front of me, it disappears. I have the latest update on both cars. Does my s75D have a faulty radar sensor? The service center said it was because they don't have the software yet for AP2.0 to detect cars on other lanes yet. Anyone with AP2.0 have a dash picture of other cars around in other lanes in front of them? I will get some picture this weekend.
