For California state officials, the new federal guidelines on testing and deployment of driverless cars come as a bit of a relief. Until this week, the absence of U.S. government guidance had left the state Department of Motor Vehicles -- generally in charge of registering vehicles and issuing drivers' licenses -- to take the lead role in drafting regulations to ensure the safety of self-driving vehicles. Though the federal guidelines issued Tuesday are short on specifics, the Department of Transportation will take responsibility for regulating the driving hardware and software, and it has devised a model state policy that probably will take the pressure off individual state agencies. That policy, issued jointly by the Department of Transportation and the National Highway Traffic Safety Administration, could result in changes to current California draft regulations on autonomous vehicles. "You can imagine how the California DMV would be struggling, with no technological background or engineers at their disposal, trying to figure out whether a particular autonomous vehicle is or is not safe enough to be deployed," said Robert Peterson, a law professor at Santa Clara University.

U.S. stocks inched higher Tuesday in another cautious day of trading as investors kept an eye on central banks in the U.S. and Japan. Healthcare and household goods companies led the way, while energy companies slipped. Major market indexes were higher all day but returned most of those gains at the close of trading. They rose just enough to cancel out Monday's small losses. Drug companies helped healthcare stocks make modest gains, while Exxon Mobil fell on reports that it's being investigated by securities regulators.

Puskar, AP) SAN FRANCISCO - Self-driving car advocates and observers are reacting with cautious approval Tuesday to the government's 112-page directive on the transformational technology. "The devil is in the details, so we will want to take a good hard look before we comment," says David Strickland, general counsel for the Self-Driving Coalition for Safer Streets, which advocates for Ford, Google, Uber, Lyft and Volvo. Strickland is also a former administrator of the National Highway Traffic Safety Administration. "We see this document as evolutionary," he told reporters on a conference call. "But we appreciate their effort, and the iterative process."

Companies from the Motor City to Silicon Valley welcomed the Obama administration's new self-driving car policy this week, but there is still a long road ahead full of obstacles before robots entirely replace humans as motorists. For auto makers and technology firms, the guidelines detailed Tuesday represent an early victory that steer clear of regulations with legal force and pressure states to avoid developing conflicting rules that could frustrate rollout efforts. But the government's unwillingness for now to aggressively draft firm, prescriptive rules shows how unprepared some regulators, urban planners and insurers are for an autonomous overhaul. Questions remain about whether the federal government will ultimately need to unwind decades of safety regulations to accommodate for vehicles that don't have steering wheels, brake pedals and other features designed for human interaction. Assuming manufacturers can overcome all the technical challenges of building an autonomous car, the burgeoning field would change the fabric of everyday life in a way that hasn't occurred since automobiles replaced horse carriages.

The U.S. government wants to help you take your hands off the wheel. The Department of Transportation on Tuesday issued its Federal Automated Vehicle Policy, which outlines how manufacturers and developers can assure safe design of driverless vehicles, tells states what responsibilities they will have and points out potential new tools for ensuring safety. Regulators say they want to prepare for the transition to self-driving vehicles, which they say will save money, time and lives.

At a recent Further With Ford event their futurist, Sheryl Connelly, talked about the growth of our world's mega-cities. She used Beijing China as an example. Beijing has 20 million people living in its metropolitan area. A typical driving commute is 5 hours! They have one highway with 50 lanes.

Ahmad Khan Rahami, the man suspected of planting a series of bombs in New York and New Jersey over the weekend, praised Anwar Awlaki in handwritten notes found on his person after he was wounded in a shootout Monday. FBI agents recovered a notebook from Rahami after he was wounded by police in Linden, N.J., a U.S. official told the Los Angeles Times. In the notebook, Rahami describes his affinity for Awlaki, the American-born Islamic cleric who became a leader of Al Qaeda in Yemen. Awlaki was killed in a CIA drone strike in 2011, but his legacy has spread among jihadists thanks to online audio and video sermons. The notebook also contained ramblings about the Boston Marathon bombers, the official said.

Machine learning, autonomy, and artificial intelligence are being explored as key new areas for cybersecurity. What is their history and likely future? As we rely more on autonomous machines for our security, what are the benefits? How can policymakers keep pace? A panel of leading experts will explore the issues from the perspectives of computer science, political science, ethics and law.

U.S. Transportation Secretary Anthony Foxx.outlines his department's intial guidelines for regulating autonomous vehicles. Federal safety regulators will issue a broad framework today for developing, testing and deploying autonomous vehicles, which are coming to market before undergoing many tests human-driven cars must meet before they are offered to consumers. The framework contained four sections -- vehicle performance guidance, a model state policy, current regulatory tools and modern regulatory tools. The Department of Transportation and the National Highway Traffic Safety Administration will listen to public and industry comment for the next 60 days. In addition to the four sections, DOT Secretary Anthony Foxx discussed what he called a 15-point safety assessment that will govern how NHTSA proceeds in the uncharted territory, where software, not humans, operates vehicles.
