This comment is legit! So many of these comments here are wildly biased to people's own personal experiences (usually the male/female Karens are the most noisy). You make many good points here.

My question(s): Why do you think Uber works so well in SF? Why don't they get trapped on Market Street with crawling speeds?

I lived in NYC (Manhattan) many years ago and I always felt that when I needed a taxi (cold/snow/rain), they were hard to get. As a result, I almost never took a classic yellow cab in NYC/Manhattan.
