Dedicated lanes for autonomous vehicles are coming -- so get prepared

I'm talking about vehicles that can function without any human intervention. But while the tech itself is evolving and going through growing pains, there's a problem: inadequate road infrastructure. While there's been huge investment in developing vehicular autonomous driving technology, there's been little by cities in the infrastructure necessary for vehicles to communicate with each other (vehicle-to-vehicle), or their surroundings (vehicle-to-vehicle infrastructure). For example, digital signage and traffic signals that can communicate with vehicles -- or pedestrian detection systems -- can "teach" a road to warn a driver when a pedestrian is at risk and feed data into a vehicle. So, the question is: do we need dedicated lanes or corridors for autonomous vehicles?
