I think there are some situations like merging on a busy highway where something like a theory of mind is at least a little bit useful so you can negotiate entry. If you don’t, the car is either going to be too aggressive or too timid.

That’s something completely different because you follow right of way laws and can gauge if you can merge or not safely based on their speed you sure as hell not watching what look they give you through your side mirror. And the “theory of mind” comes to assume the other driver doesn’t want to cause an accident either and will slow down at which case the estimation can be broken to math such as would they have to slow down given the average response time and their speed. As a person you have no idea as well if they are drunk, paying attention or not the only thing you can see is how fast they are going and usually if they are going well above the speed limit you’ll assume they are jerks and won’t let you merge which luckily is simple enough for the car to do as well

  Facial expressions aren't required here - even reading the basic behavior of a car being driven by a human involves theory of mind. Some people are actual [insult]s and will not let you merge or otherwise not play a game theoretic optimal strategy.

    Right you don’t need to see someone’s face to guess what they’re thinking any more than you need to see their brain. You can infer motivations and intentions based on how they’re driving. If you turn on your blinker and the guy in the lane next to you speeds up to close your available space, you have a pretty good idea of what they’re trying to do. I’m not sure if there’s an algorithm that will figure out if other people on the road are complete fucking assholes that you want to avoid.
