I've always wondered if TCP and networking design could be applied to autonomous traffic... basically think of every car/train as a packet and ensure no collisions...

Which networking protocol best maps to this?

And what if we had smart traffic lights that were aware of every car in an surrounding area of an intersection...

I mean FFS certain tech companies track all vehicles that drive by/near their corporate campuses and report that back to the city...

And that's almost a decade old now...

So apply the same but report the data back to the traffic management system which is also trained on all the traffic patterns for a given intersection to best optimize for their patterns...
