a) need other and probably better sensors b) need to admit true self driving is a heck of lot more complicated. (consider all the things most drivers subconsciously handle with barely a thought that in fact a computer would have to “see,” acknowledge and compute if action is needed and possibly act on while also dealing with the multitude of other factors . They have things mistaking big obvious things and hitting them. The common analogy of a plane autopilot is apples to oranges. The sky is more or less empty: some birds, weather…but air traffic controllers work very hard to keep planes a fair distance away from each other.
Perfect time to move to Vivaldi, Brave, Librewolf, etc etc that wont be following suit. (yes the list does also include Firefox…but they bought an ad company and in my opinion are now compromised)
