Riding with personal driver, without cash!

When you got confuse and want some ride at San Fransisco bay area, you can depend on ubercab. Ubercab is service that deliver fleet at your place and you can pay it directly to your credit card.
The highlight for this system is interactive communication is using iphone application, including give rate for both you and the driver.
For using this service, just follow video on their website. It's very simple, I'd like to use that service when I arrive at bay area.
