I've enjoyed the thoughtful posts to this thread, few as they may be. But the chief reason I posted it had to do with the effects on the auto industries, including suppliers, here and worldwide and the potential effects on the economy (which is why I posted it in this forum). If no one has thought about it, perhaps soon would be a good time to start.
From horse drawn carriage to horseless carriage to automated horseless carriage. Things change yet stay the same.
If there's significant shift towards hire over ownership then presumably as a population we'll need fewer cars and demand from the manufacturers will decrease. That's one outlook.
Then again if automation is effective and leads to highly efficient road use, then train and bus travel could become obsolete. Standing on an overcrowded subway platform during rush hour and stepping into an even more overcrowded train seems so primitive. The door-to-door autonomous model is surely the future.
There will always be those who love their cars and the hire model doesn't work so well when you have specific requirements such as child seats or/and a dog cage, tow hitch, etc. So ownership will never go away and the manufacturers will probably still be selling us the dream of car ownership in many decades to come.
