I suppose as an urbanist I'm supposed to embrace new things like Uber. I think there are good reasons to have a well-regulated taxi market in cities. Pricing should be transparent. Revenues should be such that a hail-able cab market exists in the denser parts of the city.
But, aside from all of that, I am so tired of people complaining about freaking Uber. It's like everyone is discovering that their new boyfriend is a jerk, but maybe next time he'll be nicer. Let it go.
It's a luxury car service.
