Drones Still Face Major Hurdles In US Airspace 166

coondoggie writes "Communications and effective system control are still big challenges unmanned aircraft developers are facing if they want unfettered access to U.S. airspace. Those were just a couple of the conclusions described in a recent Government Accountability Office report on the status of unmanned aircraft (PDF) and the national airspace. The bottom line for now seems to be that while research and development efforts are under way to mitigate obstacles to safe and routine integration of unmanned aircraft into the national airspace, these efforts cannot be completed and validated without safety, reliability, and performance standards, which have not yet been developed because of data limitations." The FAA and others seem mostly concerned about the drones hitting things if their GPS and ground communications are both disrupted.

Paris To Test Banning SUVs In the City 509

thecarchik writes "Paris may be the first city to experiment with such a policy. Next year, it will begin to test restrictions on vehicles that emit more than a certain amount of carbon dioxide (CO2) per kilometer — the measure of a car's contribution to greenhouse gases. An official within the Parisian mayor's office, Denis Baupin, identified older diesel-engined cars and sport-utility vehicles as specific targets of the emissions limit. Residents and travelers have responded by buying thousands of electric cars, including the low-speed fiberglass G-Wiz — despite major safety concerns with the vehicle."
