but this is exactly the sort of political cover the politicians need. nobody wants to be the politician that says "lets raise the speed limit here to 55MPH", but if everybody drives 55 and all of a sudden there's a bunch of self-driving cars going 50 and people are getting annoyed at the road getting blocked up, changing traffic rules to conform to reality becomes a lot more possible.
