With all that talk on autonomous vehicles, where are the smart roads to support this?

After driving home yesterday, mostly up the M6, there were lots of road works cordened off, but with no one there.  


With the big push for autonomous vehicles, driverless trains and taxis and the discussions around this, when will we be in a position to offer smart roads to manage the traffic rather than cones and signs?  Everyone sitting at 50mph for long stretches when there was no real need, there seems to be a lack of joined up thinking between those offering the autonomous vehicles and the current road system we have in the UK.

  • The obvious answer would be when 100% of the vehicles on the road are smart.


    But smart cars are paid for by their owners.  Roads are paid for by national and local government, who can't even afford to re-surface our roads regularly, let alone upgrade them all to smart roads.


    In any case, would you want to be the person making repairs in the middle of the highway, protected from the oncoming traffic by nothing more than a wireless beacon?
