Thanks, this discussion is going well. I want to add that it wasn't nhtsa, it was Tesla's data which nhtsa cited without any fact checking. But since Tesla has been parroting nhtsa's citation, they have since then withdrawn their support for Tesla's data. You would have read that in the article. Further we need to compare not only pre-aeb vs aeb vs aeb+autosteer, but also aeb+lane_keeping_assist, which we unfortunately won't have.
So, let me reiterate -- we agree that autosteer is lane keeping assist given more responsibility. If that's helpful to the driver or dangerous as it distracts him is a debate were should have with better data, which we don't have. Unfortunately, I personally don't trust Tesla giving data without any hidden unsaid caveats, given their behavior till date.
However, there is another topic we should talk about. Do you think improving autosteer lane detection with vision will make a car driverless capable? Because that's precisely Tesla markets their technology as, with coast to coast drive, or cross country summon, or driverless taxis. I personally don't believe a line following robot is enough for self driving. Infact, I like Google's approach more, where they drive only when the road is free of any object (3d mapped by lidar).
Even then, I don't think that's enough either. For example, say a ball bounces on front of you. I stop expecting a child or a dog running after it. I think driving means interacting with the environment, and responding appropriately to it, and would require a general AI.
