And here, as a senior, I've been planning and working towards the day when I won't be able to drive.  I can see it now:  A daft old man being driven around to who-knows-where by an autonomous vehicle.  Is this vehicle going to come on its own by my thinking about it?  How will it know where I want/need to go, and what will I do when I get there?  Will it boot me out?  How will I pay for this service?  Inquiring minds want to know.
