The comment I replied to was suggesting that vehicle automation would progress so rapidly that it would be practical to start working on such a ban as soon as ten years from now. I'm not disputing that such a ban might eventually become a good idea, but for it to become practical so soon, we'd have to be much, much further down the road to full automation than we are now.
If fully-automated vehicles become commercially available (which seems likely at some point, though not in the immediate future), we will likely see rapid adoption in the applications where they are very well suited, followed by a long, slow, gradual trend toward broader usage. The hardest cases will be the ones sticking around longest, and one can't simply legislate them out of existence. Just replacing a small percentage of the fleet won't come anywhere close! It's only when automated cars have become so dominant that only a small percentage of the fleet still depends on manual drivers that it will become practical to start talking about a ban on manual operation.
