What about when the car is about to collide with something you cannot see from a remote point of view, or when the positions and/or velocities are distorted from the longer perspective? There are many common situations where hazards that would usually be visible from the driver's seat are obscured when looking at the car from a distance.
Also, people generally have to be trained and pass a test demonstrating basic competency at driving and pass a vision test. These tests don't include the slightly different skills/vision required to safely judge driving a car from a distance, so why would you assume a licensed driver is even capable of operating dangerous machinery to do something outside the scope of that license?
It’s bs
You can’t, I can’t, no can perceive angles appropriately from outside the car at distances that keeps the feature safe and makes the feature useful (50 yards out)
That sounds like the issue with the chap who tried it in his driveway.
(My feeling is that if the feature isn't more reliable than a 95th percentile human for the subset of functionality, it probably shouldn't be released.)
