The driver probably has it in "assertive" mode. Outside of assertive mode it is actually annoyingly conservative. So much so that I often take manual control at turns to avoid impatient drivers honking at me as it inches through the intersection.

With that said, I hate driving in Boston, so much so whenever I go there I park outside the city and take the T (subway) the rest of the way. I would not turn on FSD in Boston in a million years.

I live in a mid-sized city much smaller than Boston and it does "ok" but even there I take manual control when downtown.
