I have to assume that tesla's cars aren't confused by those things either, for the most part. The difference is that most car's emergency brake systems act when a driver has failed to respond; the driver and the computer are acting in concert. Tesla has designed and marketed their system as if it worked separately from a focused driver. In the rare instances that their system fails, it is much less likely that the human driver has been paying attention and will brake manually.
I just looked up the subaru system. In the emergency braking case, they clearly claim that their system acts only if the driver has failed to brake. That means, for example, that it will brake much more abruptly than a human would, since it is waiting for the last moment before braking. Their lane following technology behaves similarly. Tellingly, it is called "eyesight", suggesting it is merely an extra pair of eyes, rather than "autopilot", which suggests that it can drive on its own.
- eightails 5y agoI 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.
- hanche 5y agoI drive a Kia e-Soul myself, and while I keep the lane keeping assist/alarm on most of the time, I definitely disable it on narrow, twisty roads. Otherwise, the alarm goes too often, especially when I move out closer to the shoulder to make room for meeting traffic.
