Isn’t that what turn signals are for? Car body language is somewhat location-dependent. Rural Missouri has more cautious drivers and downtown NYC more aggressive drivers. Seems complicated to modify the car’s behavior at such a fine level, but perhaps it’ll happen once the bigger issues are worked out. On-board, personalized learning from your commute would be a neat selling point.

Yes, social signals are location dependent. But driving in traffic is a social activity. And ignoring that strikes me as a big issue indeed.

Even the enforcement of rules and the expectation on that are location dependent. Someone I know walked on a crosswalk in a southern european country, expecting that this will be honored like it is here. Ended up in hospital for two weeks. No driver there expected it.
