Exactly. The tests and regulations for self driving vehicles only need to ensure this. That it has been taught to the limits of what can be done in an experimental setting, before it is allowed to be on public roads.
Right now this is not the case. A company can put a SDV on road, that is not even capable of avoiding hitting a pedestrian right in front of it in plain sight at more than breaking distance. I mean, there is nothing to ensure this does not happen. That is my whole argument.
There should be a minimum benchmark that any experimental SDV should pass consistently to be tested on public roads. There should also be some process to ensure the continued validity of the license thus given. For example, it should only be valid until a software/firmware update.
I short, authorities along with engineers and company execs need to sit down and think this through and create a framework before this program can continue..
