In general though, I've found Uber experiences to vary significantly by region. In Salt Lake, I usually sit in the front seat, drivers are chatty, and the whole thing feels like "someone giving you a ride". In NYC, by contrast, I mostly sit in the back (a lot of the time the driver will block off the front passenger seat), drivers don't tend to talk, and the whole thing feels like a cab ride.
In fact, I would guess that many Uber drivers in NYC are/were taxi drivers.
I had a guy who implied that he'd like a positive rating. Only one out of many.
I realize that EB and SF drivers probably stick to their preferred areas. I'm not disputing your experience, only adding my own.
I've stopped taking Uber for this reason for those "marginal" trips where I might be tempted for the convenience vs. public transit. I see tip begging no different than being asked for change on subway, and if I have to potentially deal with it either way I'll just take the cheaper option.
