Humans can make assumptions about humans better than machines. For example there was a trailer with a tire that blew out in front of me. It was rapidly slowing. I checked my mirrors and was being tail-gated too closely to hit the breaks. There was a car in the lane right of me, and lane right behind me.

I merged hard right before it was clear. I assumed the car on my right would do the same, and the driver further behind would break in time. They either made the same assumptions as me or took my queues and acted accordingly and everything turned out ok.

It is pretty amazing how people can coordinate on-the-fly.
