Have you driven in London? (Or other comparably busy and narrow city - even NYC at least has 'American-width' roads.)

It's not technology that's required, barring perhaps flying car technology.

If every way is busy, you can't just wait eternally, you have to communicate with other drivers as parent commenter said, maybe let a couple of people go, and then realise when you just need to go for it and 'force' someone to wait for you if they're not otherwise going to.

It will be really awesome to see a car do that safely and autonomously.

There'll come a time, perhaps, when two cars are flashing their headlights at each other to communicate, for no real reason other than "that's how human-driven cars did it in the old days"!
