The features hold tremendous potential to reduce deaths and injuries by eliminating collisions or mitigating their severity, safety advocates say. The council and the University of Iowa, along with the Department of Transportation, are kicking off an education campaign Wednesday to inform drivers on how the safety features work. Some manufacturers offer CDs or DVDs on how to use safety systems, but "most of the time drivers don't actually take the time to review them," said Peter Kissinger, president of the AAA Foundation for Traffic Safety. A study by the foundation of early safety technology adopters found that some drivers believed collision warning systems would brake to stop their vehicles for them, when actually the systems only alert drivers to an impending collision. Ray Harbin, 67, AARP's state volunteer coordinator for driver safety courses in Montana, said the frustration seniors experience learning new-car technology is similar to what they feel when they are forced to adapt to software changes in computers like a new version of the operating system. Tom Pecoraro, a retired police officer who owns "I Drive Smart" schools in California, Maryland and Virginia, said the state-required curriculums taught in driving schools are typically about 15 years behind the latest technology. Classes introduce students to anti-lock brakes and airbags but are unlikely to mention adaptive cruise control and automatic braking.
