Google: Driverless cars are mastering city streets

LOS ANGELES--Google says that cars it is programming to drive themselves have started to master the navigation of city streets and the challenges they bring, from jaywalkers to weaving bicyclists — a critical milestone for any commercially available self-driving car technology.

Despite the progress over the past year, the cars have plenty of learning to do before 2017, when the Silicon Valley tech giant hopes to get "autonomous driving" technology to the public.

None of the traditional automakers has been so bullish. Instead, they have rolled out features incrementally, including technology that brakes and accelerates in stop-and-go traffic, or keeps cars in their lanes.

"I think the Google technology is great stuff. But I just don't see a quick pathway to the market," said David Alexander, a senior analyst with Navigant Research who specializes in autonomous vehicles.

His projection is that self-driving cars will not be commercially available until 2025.

Google Inc.'s self-driving cars already can navigate freeways comfortably, albeit with a driver ready to take control. In a new blog post, the project's leader said test cars now can handle thousands of urban situations that would have stumped them a year or two ago.

"We're growing more optimistic that we're heading toward an achievable goal — a vehicle that operates fully without human intervention," project director Chris Urmson wrote. The benefits would include fewer accidents, since in principle machines can drive more safely than people.

Urmson's post was the first official update since 2012 on a project that is part of the company's secretive Google X lab.

In initial iterations, human drivers would be expected to take control if the computer fails. The promise is that, eventually, there would be no need for a driver. Passengers could read, daydream, even sleep — or work — while the car drives.

That day is still years away, cautioned Navigant's Alexander.
