I think the points that have been raised in this thread are all quite valid. Just to add another: I wonder if Tesla's driver assistance systems has been designed to minimise false-positives in comparison with those of other manufacturers. When driving a friend's Subaru on a road trip a while ago we all commented on the lane-keeping alarm being overzealous, and ended up disabling it altogether to shut it up (this is on somewhat narrow b-roads). I've read of similar complaints from automotive journalists regarding various other manufacturers. In comparison, I've barely ever experienced false positives from the model 3's lane-keeping assist, even on similar roads -- maybe once or twice ever. Minimising false-positives is important for system efficacy, as otherwise people will simply disable it. But I do wonder if this comes at the expense of increasing the chance for false-negatives, which are far more dangerous. Is trading 100 false alarms for a single missed obstacle worth it? I'm not sure.
