Once we get to the point where all cars on highways are automation capable, if not outright enabled, there should be the option to have speed dictated by road conditions so that, under optimal conditions, the system could adjust speed up, and adjust speed down as conditions worsen. That is, allow speed to be variable and dependent on conditions on the road (at that particular section). Or, they could rate different lanes at different speeds, or a combo allowing people to tell the system where to merge into.
There is the complication of less capable cars --so that maybe bunches of cars (those part of a wave of traffic) would have to submit to the safety levels of the least safe vehicle. (Let's say a bunch of high performance sports cars and an economical car which isn't designed for hugging the road nor has grippy tires; or, throw in a cargo truck).
Maybe the rightmost lane could be reserved for non autonomous vehicles like classics and holdouts (people afraid of automation/driverlessness).
Given that speeding tickets would be rare, the state could impose fees based on a combination of emissions and also road wear (tonnage, for example) to offset lost revenue.
