When I first time use this app and book a taxi, I confused what is the next procedure. But app give completely satisfication like driver contact, car number and live location of the taxi and most important driver backcall to the customer and pick and drop position is perfect.
This is the great service provided by the uber company.
We have save time, money and easily/safe visit the destination point.
One more thing is that a ordinary charges give us perfect facilities.
And my feeling like that i'am a car owner. And my driver is drive my car.
