A big mistake I see in articles about Uber is calling it a "ride-sharing service." Nonsense! Uber is no more a "ride-sharing service" than my local gas station is a "fuel-sharing service." Uber is an automated dispatch service that also (supposedly) sets standards for its cars and drivers.
The idea of passengers "crowdsourcing" inspections is a fine Randian fantasy, but come on: have you ever checked the brake pads on a taxi or an Uber-dispatched car before you rode in it? I didn't think so.
All Uber has really done is automate the transportation company's dispatchers and phone operators out of a job. Other livery, taxi, and gypsy cab services are now writing their own apps, so Uber is probably good for no more than another 3 - 5 years, and will start showing signs of stress in 2017 or 2018.
