It will deadlock in the center because the car lanes are used for two directions. Unless you upgrade those unidirectional lanes into bi-directional pairs of lanes.
And it will still deadlock, so you have to put a round-robin semaphore in the middle.
Sorry I’m late for work, I got sucked into a black hole again. No, I didn’t take a picture of the event horizon, you should just take my word for it. I wouldn’t even be late if it weren’t for the time dilation.
The center should put you on an out-spiraling bridge that feeds traffic back into the outermost lane. Then even the most indecisive drivers are accommodated. Or just a deep pit of punishment.
