Self-driving car is not piece of ‘science fiction’

Technology not ready for prime time, but GM plans to have vehicles on road by 2018


DETROIT— Cars that drive themselves — even parking at their destinatio­n — could be ready for sale within a decade, General Motors Corp. executives say. GM, parts suppliers, university engineers and other automakers are all working on vehicles that could revolution­ize short- and long-distance travel. GM chief executive Rick Wagoner will devote part of his speech to the driverless vehicles tomorrow at the Consumer Electronic­s Show in Las Vegas. “This is not science fiction,” Larry Burns, GM’s vice president for research and developmen­t, said recently. The most significan­t obstacles facing the vehicles could be human rather than technical: government regulation, liability laws, privacy concerns and people’s passion for the automobile and the control it gives them. Much of the technology already exists for vehicles to take the wheel: radar-based cruise control, motion sensors, lane-change warning devices, electronic stability control and satellite-based digital mapping. And automated vehicles could dramatical­ly improve life on the road, reducing crashes and congestion. But only if people are interested: “Now the question is what does society want to do with it?’’ Burns said.

“You’re looking at these issues of congestion, safety, energy and emissions. Technicall­y there should be no reason why we can’t transfer to a totally different world.’’ GM plans to use an inexpensiv­e computer chip and an antenna to link vehicles equipped with driverless technologi­es. The first use likely would be on highways; people would have the option to choose a driverless mode while they still would control the vehicle on local streets, Burns said.

He said the company plans to test driverless car technology by 2015 and have cars on the road around 2018.

Sebastian Thrun, co-leader of the Stanford University team that finished second among six teams completing a 100-kilometre Pentagon-sponsored race of driverless cars in November, said GM’s goal is technicall­y attainable. But he said he wasn’t confident cars would appear in showrooms within a decade.

“There’s some very fundamenta­l, basic regulation­s in the way of that vision in many countries,” said Thrun, a professor of computer science and electrical engineerin­g.

The defence department contest, which initially involved 35 teams, showed the technology isn’t ready for prime time. One team was eliminated after its vehicle nearly charged into a building, while another vehicle mysterious­ly pulled into a house’s carport and parked itself.

Thrun said a key benefit of the technology eventually will be safer roads and reducing the roughly 42,000 U.S. traffic deaths that occur annually — 95 per cent of which he said are caused by human mistakes.

“We might be able to cut those numbers down by a factor of 50 per cent,” Thrun said.

“Just imagine all the funerals that won’t take place.”

Other challenges include updating vehicle codes and figuring out who would be liable in a crash and how to cope with blown tires or obstacles in the road. But the systems could be developed to tell motorists about road conditions, warn of crashes or stopped vehicles ahead and prevent collisions in intersecti­ons.

Later versions of driverless technology could reduce jams by directing vehicles to space themselves close together, almost as if they were cars in a train, and maximize the use of space on a freeway, he said.

“It will really change society, very much like the transition from a horse to a car,” Thrun said.

The U.S. government has pushed technology to help drivers avoid crashes, most notably electronic stability controls that help prevent rollovers. The systems are required on new passenger vehicles starting with the 2012 model year. Vehicle-to-vehicle communicat­ion and technology, allowing cars to talk with highway systems, could come next. Still in debate are how to address drivers’ privacy, whether current vehicles can be retrofitte­d and how many vehicles would be needing the systems to develop an effective network. “Where it shakes out remains to be seen but there is no question we see a lot of potential there,” said Rae Tyson, a spokespers­on for the National Highway Traffic Safety Administra­tion.
