And again, 'who is my autonomous car going to kill today?' is the 'cool' end of the conversation, but I haven't seen a lot of people talking about what autonomous vehicles might mean once they're here. So, imagine when all vehicles are autonomous and traffic management itself is about the traffic system managing the movements of all cars. Now imagine I'm wealthy and rest of hubski isn't. I subscribe to a premium service called 'Get Me There On Time' which means that I get automatic preferential traffic treatment. Your cars will merge out of the passing lane and slow down when my car catches up to yours. Doesn't matter how late you are, you're a standard subscriber and I am not. Or imagine that as a premium subscriber, my journey is going to clash with the journey of an autonomous ambulance going into a poor neighbourhood. Who wins? Or, I'm a platinum premium subscriber, and one of my benefits is that on certain classes of suburban roads, all traffic will come to a stop as I pass as long as the delay caused to others is calculated as being no more than an average of, say, 3 minutes. This is because, as a platinum premium customer, my status is immediately obvious because my car is moving and yours isn't. There's some interesting possibilities and consequences wrapped up in this technology.
