Autonomous vehicles operating on limited routes (geofenced) at first is exactly what is described in the article, so it's not clear to me what you disagree with.
I suppose you could say that, but I’m saying it’ll be late rather than not be possible. I suspect roads will start being built with automation in mind for example, and push bikes might be required to have a small transceiver to alert the cars AI to their whereabouts. I think Ford are saying here that it just won’t be good ever, I’m saying it will be better, later and slower to be everywhere but will still exist.
