Just returned from a week in San Francisco where I used Uber 90% of the time with 0 problems. Well, not entirely true. I asked to have an Uber sent to 18th Street when I was on 18th Avenue and naturally the Uber went to 18th Street, as I had requested but I wasn't. Cost me $5.00 but the honest mistake was mine and not with Uber.
I fail to understand why people use cabs when Uber is available. Any time, any place in the city at a reasonable price I am almost magically whisked away to my destination of choice and usually with less than 2 minutes wait time.
No exchange of funds in the vehicle, billing is automatic so I can travel without holding currency. How great is that?? Go Uber!!
I'd like to try driving for them and tray out the other side. All the drivers I spoke with, and I spoke with them all, loved the Uber set up that allowed them to work or not work, take a break for 5 minutes, 5 hours, 5 days or however long you want, get to choose if you work night or day, weekends or weekdays, holidays or no holidays. What other job gives you those options???
I wonder how many of the folks who gave Uber 1 star are still using Uber?? My guess is most of them still are as Uber is still way ahead of whatever choice is second behind Uber.
