Weird thing has happened to me -- 3 times, maybe four. I am driving along, all of a sudden I get a rapid beep of the front collision warning, there is a red image of a car in front of mine on the dashboard, right in front and flickering red for a second or two... but there is no car in front of me. Then the whole thing disappears and back to normal. A ghost in the machine if you will Has not been a safety issue, and since this only happened a few times, not a huge deal. Just wondering if others have experienced this as well. Thanks.
