How would that work? You have the AI explain its reasoning - and trust that this is accurate - and then you decide whether that is acceptable behavior. If not, you ban the AI from driving because it will deterministically or at least statistically repeat the same behavior in similar scenarios? Fine, I guess, that will at least prevent additional harm. But is this really all that you want? The AI - at least as we have them today - did not create itself and choose any of its behaviors, the developers did that. Would you not want to hold them responsible if they did not properly test the AI before releasing it, if they cut corners during development? In the same way you might hold parents responsible for the action of their children in certain circumstances?
