There's a lot of work that will need to be done with the infrastructure but this is inevitable. There are the experimental cars out there now that do it based on GPS positioning. There are a number of higher end vehicles that will "almost" do it. And most newer vehicles have safety devices that help keep you in your lane, stop you, etc..
For this to work, I think you will need such things as devices implanted in the roads that the cars communicate with as well as devices in each car that communicate with each other. The vehicle needs to know precisely where it is at on the road and for safety reasons, the cars close by need to be communicating with each other to avoid collisions.
This isn't something I think you'll see in the next 5 years but certainly within the next 15 to 20 years, perhaps even sooner.
