In SF the quality of Uber's service has dropped so dramatically in the past 3-4 months that I no longer use it anymore. It's completely commoditized and I have no qualms about switching to Lyft when they have a better product.
1) I can't see estimated time but lots of cars around. I then book and it estimates > 12min wait time. If I cancel, it charges me $2 anyway because reasons. 2) a number of drivers cancel after 10 min of waiting - this happened 3x in a row a few weeks ago so I finally got a car after 40 min. ...
