This is always the first thing I think of when I picture a future with wide adoption of autonomous vehicles. Not only is there road-rage potential, think about the municipal revenue from traffic enforcement. The public purse will remain thirsty for the funds, but autonomous cars will be very difficult to fine (either because they don't break the law or because every ticket gets disputed with hard data from companies that can afford to defend themselves). So what will happen? People driving older cars will start to become "over fished". As time goes on, it will only be poor people getting tickets (even more so than today) and therefore disproportionately minorities, and the social unrest between those people and an antagonistic police force will worsen. The way laws are made is an interesting and complicated topic. Most people have an innate understanding as to what is "correct", when when the laws don't match up then there are problems. They keep the speed limits a little below that number because then the police can pull over cars they don't like at will, and because of the ticket revenue. Honestly, I think once autonomous vehicles pass the 50% mark, they will have to increase the speed limits just to keep everyone safe.
