I don't know. Boston and New York may have a culture of taking whatever right of way you think you can get away with. The West Coast historically at least was more known for enforcing jaywalking though given the current state of SF I'm not sure that's still true. Boston/Cambridge also has a huge influx of students every year, many of which are pretty clueless about navigating an urban environment safely.

Totally fair. Things I might find challenging as a human unfamiliar with a given location (though GPS tends to help a lot) are probably different from an autonomous vehicle dealing with a lot of borderline crazy behavior by other cars, cyclists, and pedestrians darting out into traffic. A person also can just process so many inputs at once so you get into situations that are challenging in part because so much is going on.
