We could simply mandate it that all "express" lane projects be marked to ease use of self driving cars. express lane is the new word for toll lanes. we could even convert HOV lanes to support self driving cars provided they are in that mode. the benefit is early adopters are more likely to pay for express lanes if that includes being able to go nearly hands free the whole drive and it is in a controlled environment with very limited access points. which brings up something else. how to communicate to others that a car is under the control of the onboard systems. we have DRLs and third brake lights. So something at both ends?
