Self-driving cars aren't ready for roads

WASHINGTON (AP) — Self-driving cars are more likely to hurt than help public safety because of unsolved technical issues, engineers and safety advocates told the government Friday, countering a push by innovators to speed government approval.

Even a trade association for automakers cautioned the National Highway Traffic Safety Administration at a public meeting that a slower, more deliberative approach may be needed than the agency's plan to provide its guidance for deploying the vehicles in just six months.

There are risks to deviating from the government's traditional process of issuing regulations and standards, Paul Scullion, safety manager at the Association of Global Automakers, told a public meeting on self-driving cars hosted by NHTSA.

Issuing new regulations takes an average of eight years, NHTSA has said.

"While this process is often time consuming, these procedural safeguards are in place for valid reasons," Scullion said. Working outside that process might allow the government to respond more quickly to rapidly changing technology, but that approach would likely come at the expense of thoroughness, he said.

Mark Rosekind, NHTSA's administrator, said the agency can't wait because early self-driving technologies are already in cars on the road, including automatic emergency braking that can stop or reduce speed to avoid or mitigate a collision. Another safety option on some vehicles automatically steers vehicles back into their lanes if they start to drift without the driver first using a turn signal.

"Everybody asks, 'When are they going to be ready?' I keep saying they're not coming; they are here now," Rosekind said.

Without federal instructions, "people are just going to keep putting stuff out on the road with no guidance on how do we do this the right way."

Rosekind emphasized that he sees self-driving cars as game-changing technology that can someday save the lives of many of the more than 30,000 people killed each year on the nation's roads.

A Ford Motor Co. official recently told a Senate committee that the automaker expects to deploy self-driving cars within a few years through a partnership with the car-sharing service Lyft. Google, a pioneer in the development of self-driving cars, is pushing Congress to give NHTSA new powers to grant it special, expedited permission to sell cars without steering wheels or pedals.

But many of those who addressed the meeting, the first of two the agency has scheduled as it works on the guidelines, described a host of situations that self-driving cars still can't handle:

—Poorly marked pavement, including parking lots and driveways, could foil the technology, which relies on clear lane markings.

—Bad weather can interfere with vehicle sensors.

—Self-driving cars can't take directions from a policeman.

—Inconsistent traffic-control devices — horizontal versus lateral traffic lights, for example.

Until the technology has advanced beyond the point where ordinary conditions are problematic, "it is dangerous, impractical and a major threat to the public health, safety and welfare to deploy them," said Mark Golden, executive director of the National Society of Professional Engineers.

There have been thousands of "disengagements" reported in road tests of self-driving cars in which the vehicles automatically turned control over to a human being, said John Simpson, privacy project director of Consumer Watchdog.

"Self-driving cars simply aren't ready to safely manage too many routine traffic situations without human intervention, he said.

Rosekind said automakers are learning from the unanticipated situations the vehicles encounter and adapting their software. At the same time, he acknowledged that self-driving cars, like other systems that rely on wireless technology, can be vulnerable to hacking.

James Niles, president of Orbit City Lab, a New York think tank, told the meeting that there is a complete absence of federal regulations and standard to prevent self-driving cars from being turned into weapons by "bad actors."

"The concern that an autonomous vehicle could be used as a weapon has gone unnoticed by the general public and probably by the majority of government officials," he said.

President Obama has proposed a 10-year, $3.9 billion automated technologies program, including large-scale pilot deployments of self-driving cars around the country and funding additional cybersecurity research.
