Google driverless car: Test driven and reviewed
This isn’t damning with faint praise. It’s actually high praise for the car in question: Google Inc.’s driverless car.
Most automotive test drives (of which I’ve done dozens while covering the car industry for nearly 30 years) are altogether different.
There’s a high-horsepower car. A high-testosterone automotive engineer. And a high-speed race around a test track by a boy-racer journalist eager to prove that, with just a few more breaks, he really could have been, you know, a NASCAR driver.
This test drive, in contrast, took place on the placid streets of Mountain View, the Silicon Valley town that houses Google’s headquarters.
The engineers on hand weren’t high-powered “car guys” but soft-spoken Alpha Geeks of the sort that have emerged as the Valley’s dominant species. And there wasn’t any speeding even though, ironically, Google’s engineers have determined that speeding actually is safer than going the speed limit in some circumstances.
“Thousands and thousands of people are killed in car accidents every year,” said Dmitri Dolgov, the project’s boyish Russian-born lead software engineer, who now is a U.S. citizen, describing his sense of mission. “This could change that.”
Dolgov, who’s 36 years old, confesses that he drives a Subaru instead of a high-horsepower beast. Not once during an hour-long conversation did he utter the words “performance,” “horsepower,” or “zero-to-60,” which are mantras at every other new-car test drive. Instead Dolgov repeatedly invoked “autonomy,” the techie term for cars capable of driving themselves.
Google publicly disclosed its driverless car program in 2010, though it began the previous year. It’s part of the company’s “Google X” division, overseen directly by co-founder
Sergey Brin and devoted to “moon shot” projects by the Internet company, as Dolgov puts it, that might take years, if ever, to bear fruit.
So if there’s a business plan for the driverless car, Google isn’t disclosing it. Dolgov, who recently “drove” one of his autonomous creations the 450 miles (725 km) or so from Silicon Valley to Tahoe and back for a short holiday, simply says his mission is to perfect the technology, after which the business model will fall into place.
NOT WINNING BEAUTY CONTESTS, YET
Judging from my non-eventful autonomous trek through Mountain View, the technology easily handles routine driving. The car was a Lexus RX 450h, a gas-electric hybrid crossover vehicle – with special modifications, of course.
There’s a front-mounted radar sensor for collision avoidance. And more conspicuously, a revolving cylinder perched above the car’s roof that’s loaded with lasers, cameras, sensors and other detection and guidance gear. The cylinder is affixed with ugly metal struts, signaling that stylistic grace, like the business plan, has yet to emerge.
But function precedes form here, and that rotating cylinder is a reasonable replacement for the human brain (at least some human brains) behind the wheel of a car.
During the 25-minute test ride the “driver’s seat” was occupied by Brian Torcellini, whose title, oddly, is “Lead Test Driver” for the driverless car project.
Before joining Google the 30-year-old Torcellini, who studied at San Diego State University, had hoped to become a “surf journalist.” Really. Now he’s riding a different kind of wave. He sat behind the test car’s steering wheel just in case something went awry and he had to revert to manual control. But that wasn’t necessary.
Dolgov, in the front passenger’s seat, entered the desired destination to a laptop computer that was wired into the car. The car mapped the route and headed off. The only excitement, such as it was, occurred when an oncoming car seemed about to turn left across our path. The driverless car hit the brakes, and the driver of the oncoming car quickly corrected course.
I sat in the back seat, not my usual test-driving position, right behind Torcellini. The ride was so smooth and uneventful that, except for seeing his hands, I wouldn’t known that the car was completely piloting itself – steering, stopping and starting – lock, stock and dipstick.
Google’s driverless car is programmed to stay within the speed limit, mostly. Research shows that sticking to the speed limit when other cars are going much faster actually can be dangerous, Dolgov says, so its autonomous car can go up to 10 mph (16 kph) above the speed limit when traffic conditions warrant- Reuters
