Study finds teen drivers need more time in adverse conditions

Practice might make perfect, but not if the drills never change. In a study organized by the AAA Foundation for Traffic Study and the University of North Carolina Highway Safety Research Center, participating teen drivers averaged about an hour and a half of supervised driving each week--mostly on routine trips along the same roads. At the end of the year-long study, 47 percent of parents said there was at least one driving condition they felt their student wasn't prepared to handle.

Porsche 911 cabriolet: First official photographs

Porsche has developed an innovative fabric and composite-plastic folding roof for the 911 cabriolet as part of a push to give it a cleaner appearance, improved aerodynamic efficiency and greater levels of refinement than its strong-selling predecessor. Pictured here officially for the first time ahead of its world premiere in January at the Detroit auto show, the new open-top 911 is planned to go on sale in North America in 2012 in Carrera cabriolet and Carrera S models. Eschewing the traditional multilayered fabric structure of the 997 series 911 cabriolet, the next model (991 series) adopts a specially developed lightweight roof that uses two fabric-skinned composite plastic panels for the upper and rear part of the structure, giving it a more uniform shape together with a tauter fit that is claimed to make it more resistant than before to buffeting at high speeds.
