Everyone already knew at the time that this decision was doomed to fail. They now even doubled down to actively remove sensors from older models, to avoid the inputs interfering with the new updates. When it comes to automating and especially autonomous driving in combination with safety, one should want as much input as possible. I doubt visual can compute faster than radar/lidar, I think it was just a cost saving effort. Gladly, Mercedes and BMW show the way to autonomous driving and are allowed to actually start using the first versions on European highways.
