I think OP was talking about "crash avoidance" systems. Not systems that claim to drive the car but not really.
You're always driving, the car is just silently observing. If the car sees you're about to crash, it steps in and takes over. The opposite of Tesla's approach where you play the role of observer taking over when things go wrong.
The first approach is safe. The second approach isn't safe until full autonomy due to cognitive load and task switching delays.
- Animats 9y agoThere are many automotive "auto-brake" systems, usually controlled by a radar. Those are useful. They're usually programmed to act only when a collision is inevitable. They prevent some slow-speed collisions, and reduce the damage in some faster ones. What they don't do is take over steering. A last-second takeover of steering would make things worse some of the time.
- Swizec 9y agoDon’t Volvo and Mercedes do obstacle avoidance? Or is that still in research? I think I remember seeing videos.
- kuschku 9y agoYes they do. They take over steering, automatically drive around obstacles, etc. And this is already deployed in production vehicles today.
- ingenieroariel 9y agoCan you elaborate? Assuming for example the car is fitted with solid state lidar on the four corners and ESR on the four sides or even LIDAR. What are your thoughts on crash prevention if the car has the same hardware as a a Waymo car? (edit: to clarify, would you consider autosteering at the last minute safer than a human driver in that scenario?)
- nradov 9y agoThe next Volvo model will take over steering for collision avoidance. http://www.leftlanenews.com/volvo-xc60s-collision-avoidance-system-adds-steering-control-94788.html http://www.leftlanenews.com/volvo-xc60s-collision-avoidance-...

While its lane-keeping system won't steer during a crash, it definitely does steer to keep you centered in the lane (when it's able). That could help avoid all kinds of crashes due to inattentive lane-drifting.
- mjevans 9y agoI really don't want those on in stop and go rush-hour traffic. They're very likely to cause someone /behind/ the automated car to have an accident. (Yeah yeah, following distances; trying building enough capacity for everyone to do the proper following speed and keep distance.)
