Taxi-hailing apps like Uber and its competitors have been hitting stop sign after speed bump in their journey to actually, you know, being able to operate. Uber even had to shut down a beta in the Big Apple before the authorities gave such services the green light (with various caveats), and earlier this month, a similar win was scored in California when officials lifted local restrictions. As a result of the Golden State's leniency, Uber has started its UBERx program in San Francisco to recruit drivers who don't possess a specific taxi or limo license. That means everyone and your neighbor Bob can potentially start exchanging rides for cash, and are being promised decent compensation, completely flexible working hours, and access to a large number of clients. Luckily for fare-payers, those that wish to repurpose their whip will have to pass several tests before ferrying passengers, including a "city knowledge exam," so hopefully you won't end up on Alcatraz when you just asked Bob for a lift to Chinatown.
