Uber drivers use their own personal cars.
As of August 2016, the service was available in over 66 countries and 507 cities worldwide.
The Uber app automatically calculates the fare and transfers the payment to the driver.
Since Uber's launch, several other companies have replicated its business model, a trend that has come to be referred to as "Uberification".
The legality of Uber has been challenged by governments and taxi companies, who allege that its use of drivers who are not licensed to drive taxicabs is unsafe and illegal; some taxi driver unions have called Uber drivers "pirate taxis".
A taxicab, also known as a taxi or a cab, is a type of vehicle for hire with a driver, used by a single passenger or small group of passengers, often for a non-shared ride.
Illegal taxicabs, sometimes known as gypsy cabs, are taxicabs and other for-hire vehicles that are not duly licensed or permitted by the jurisdiction in which they operate.
