For fully autonomous driving need to happen, all cars must exchange data with each other how robots do in a factory floor. Image and depth perception can solve some problems but a crash or a vehicle can maneuver in any direction. If two self driving cars need to take a decision at a intersection, how are they gonna do it?

Do you need to exchange data with every other driver when you're on the road?

Isn’t this what turn signals, horns and brake lights are for? Not to mention making eye contact with pedestrians at crossings.

Self driving cars have turn signals, horns, and brake lights too. And can also read that data from other cars. And some of them even replicate eye-contact now.

Do factory floor robots communicate with each other in any meaningful way? I'm under the impression that they mostly just follow pre-programmed paths and all you need for that is clock synchronization.
