I’ve never driven in NYC, but I have biked and walked it. NYC may have more frequent edge cases than SF, but in terms of being able to handle urban edge cases I think SF is roughly comparable to NYC. In some regards traffic in NYC seems even more predictable. Like there’s been times I thought a motorist would gun it through a red light in NYC as would happen in SF, only to see the driver stop and then feel embarrassed for being overly cautious.
