| I have a Subaru with eyesight too. The auto-braking in Subarus with eyesight can engage in two circumstances that I'm aware of. 1: The car is travelling at 50 km/hr or less, and perceives an oncoming obstacle. 2: The car is using adaptive cruise control, and perceives that it is getting too close to the vehicle ahead. I think there are some circumstances where the designers decided that auto-braking would actually be worse. For instance, at highway speed, it's usually not possible to come to a stop quickly enough to avoid a stationary object that has somehow suddenly come into your path. Say, a deer. It's best to take your feet off both pedals and swerve around the obstacle. This reduces speed while also allowing maneuvering, something that braking works against. It also gives drivers behind you more time to react. If the Tesla system works similarly I would expect similar design decisions. However, I would expect autopilot on a Tesla to function similarly to adaptive cruise control, which will jam on the brakes when it thinks it's going to hit something. This has actually engaged erroneously on two occasions for me, on windy roads, so I only use adaptive cruise control in straight-arrow highway situations now. I've noticed that in certain weather conditions the cameras will stop being able to get good enough data to make decisions. The car disables the system and notifies me with a warning indicator. tl;dr - auto-breaking based on parallax cameras can't be deployed in every situation, and sometimes the cameras can't get a clear shot. |
