A battle for the future of transportation is being waged outside
our offices and homes. Uber and a growing collection of well-funded
start-ups, such as the ride-sharing service Lyft, are trying to
make getting a taxi as easy as booking a reservation on OpenTable
or checking a price on Amazon—just another thing you do with your
smart phone. These companies want to make owning a car completely
unnecessary. “Being out in front of the taxi industry, putting a
bull's-eye on our back, has not been easy,” says Travis Kalanick,
the 37-year-old chief executive of Uber. “The taxi industry has
been ripe for disruption for decades. But only technology has
allowed it to really kick in.”
Only a few years ago, Uber introduced the idea of allowing
passengers to book the nearest town car by smart phone and then
track the vehicle on a map as it approaches their location. After
the ride, the service automatically compensates the driver from the
customer's preloaded credit card—no awkward tipping required. It's
a simple experience and a much more pleasant way to get a ride than
stepping onto a busy street and waving at oncoming traffic.
Uber has raised $307 million from a group of backers that include
Google Ventures, Google's investment arm, and Jeff Bezos, the
founder of Amazon. It operates in 270 cities around the world and
was on track to book more than $1 billion annually in rides in
2013, according to financial information that leaked to the gossip
website Valleywag last November. In February alone, Uber expanded
to Dubai; Honolulu; Lyon; Manila; Milwaukee; Pittsburgh; Tucson,
Arizona; and Durban, South Africa.
In the process, Uber has managed to become one of the most loved
and hated start-ups of the smart phone age. Its customers rave
about the reliability and speed of the service even as they
bitterly complain about so-called surge pricing, the elevated rates
Uber charges during hours of high demand. Uber has also been
blocked from operating in several markets by regulators out to
protect the interests of consumers or entrenched incumbents,
depending on whom you ask. After customers complained about the ban
in Austin, Texas, the Austin City Council adopted a regulatory
structure for ridesharing, enabling Uber to operate in the city. In
Boston and Chicago, taxi operators have sued their cities for
allowing unregulated companies to devalue million-dollar operating
permits. Things grew especially heated recently in Paris when
incensed taxi drivers shut down highway exits to the main airports
and gridlocked city traffic.
