I saw a demo of this sort of system c.a. 2000 and it completely blew my mind. Sadly, from what I can see in the video the technology hasn't really changed. This indicates to me that the problems facing car train adoption are the same they were a decade ago: people just aren't comfortable with the technology. I think, unfortunately, this'll be as far from reality in 2020 as it is in 2010 and was in 2000.
