I have to agree with Artin's post: the blind spot detection is useless in moving traffic. It seems like that is the general flavor of this thread. Though this is not justification for an obviously flawed warning system, at least it explains why the service people at Tesla tells me: "they all do that".Yesterday I paid great attention as I was on a two lane in each direction divided highway. So to test the blink spot detection I stayed in the right lane as faster traffic was passing me on the left.
Results? Of the 25 autos that passed me on the left, not once did the blind side sensor subsystem illuminate. Ever. I wonder actually if a sensor is defective? Has anyone else tried this? My car was spotless so it was not dreck. The left sensor works when I am backing up and getting close to objects. How else to test this subsystem??
