Uber's first self-driving cars will start operating within a month

In a surprise announcement, Uber is claiming that its self-driving cars will begin operation in just a few weeks.
Uber CEO Travis Kalanick told Bloomberg Businessweek that the company is just about ready to roll out its first driverless, autonomous cars later this month in Pittsburgh. 
The cars will be a heavily modified Volvo XC90 SUVs. The cars will still have drivers supervising the rides. No word on whether you'll have to rate those drivers.
Uber did not immediately respond to a request
