I don't think that's true. Often times at night, there are long times for certain lights so the bigger throughput street can have more time on there. Human drives know about this, and will take different routes to get there. It's unclear that Cruise is mapping out light timings and their changes, although you would think they would.

yes lights let higher throughput roads have more time. i don't see why it makes my statement not true.

I take point with your use of 'correctly' because traffic engineering cannot get every car to its destination without stopping it even if it knew every destination.

Cars already do talk to various traffic lights via underground sensors and occasionally a camera. The investment required to have a fully networked traffic light system with a centralized controller would be immense, and would create an organization with a natural government given monopoly.

Your use of 'correctly' paints a world that seems ripe for more corruption and ultimately worse timings across the network. If you wrote 'better', then I wouldn't have commented. I think I'm nitpicking
