Self-driving cars will be the future, as long as they're all rock-solid on cooperation. Imagine normal intersections, with inefficient stop lights where half the cycle is idle (all the cars on the green side went through already) due to a change in traffic patterns from when they were programmed. Instead, cars that all cooperate can move through the intersection pretty well by taking turns.
About thirty percent of traffic in SF is due to people cruising around the block, looking for parking. [1]. Imagine if you could just tell your car, "go park somewhere, I don't care where", and have it come back when you need it. Heck, someone else could use it to get from A to B instead of letting it idle parked.
There's a lot of potential awesome here, but it all springs from rock-solid cooperation routines. If people manage to write aggressive / betraying self-driving algorithms, a lot of those traffic light scenarios could easily get a lot worse. Trust issues are a thing: should the car's driving routines be black-boxed? If there were FOSS car brains, would we trust people to not mod their cars to do illegal stuff? I guess traditional traffic cops could handle a lot of the same things they do now, we'd just need the standard autodrive package to account for and expect other cars to be driven in poor, uncooperative fashions.

- ChuckMcM 11y agoYet another reason to replace stop light controlled intersections with roundabouts. The roundabout is designed for cooperating drivers, stoplights just implement a worst case algorithm.
- TTPrograms 11y agoRoundabouts with unbalanced peak flow traffic can be impossible to enter if a previous entrance has a near-constant peak traffic flow. At rush hour they basically break under this condition. You could mildly gate them with lights to fix that, though.
- nitrogen 11y agoIf I am entering a roundabout from a dominant direction I try to leave enough of a gap for an attentive driver on the other entrances to get in. It seems fair, since sometimes I'm that driver who is waiting.
- toomuchtodo 11y agoRoundabouts are for humans. You can have a four way intersection without traffic control if all vehicles are fully automated; they each know when they can proceed and when to yield, with no need to wait on other vehicles except when a conflict occurs. https://i.imgur.com/uIAW6G5.gif https://i.imgur.com/uIAW6G5.gif
