No, clearly you look nothing like a man at all.

And it’s possible that Uber driver didn’t think you did either. Sometimes when I was in a position to be working constantly with the public, I got into the habit of working lots of sirs and ma’ams into my speech. Just trying to be polite and charming.

But I’d also get stuck on autopilot, and sometimes a sir would slip out without my meaning it to even when I absolutely knew the person I was talking to was a woman. Kind of weird, but I think it was some sort of autonomous response getting ahead of my conscious thinking.

Of course that might say something (not at all good) about the assumption of masculine and marginalization of feminine, but not about my perception of the gender of the person I was interacting with.

It was more of a verbal tic having to do with my too frequent interaction with people, or perhaps a symptom of allowing automatic speech patterns to take over from intentional communication.
