Not every remedy involves new technology. Sometimes it's just a matter of making dials larger so they're easier for drivers to find. A strap can be added to hold onto when getting in and out of a car. An extended mirror can help drivers avoid turning around as much. "They may extend the driving careers of some seniors, but they are certainly not a panacea," cautioned Dr. Bonnie Dobbs, a gerontology professor at the University of Alberta. She notes that many technologies could distract or confuse older drivers, which could lead to accidents. Better designed roads may also help. For example, traffic "roundabouts" that gently ease drivers into turn circles with no traffic lights could help reduce left turn-related crashes, which make up a disproportionate share of the accidents that kill older drivers. What's not being addressed is how to keep older Americans mobile after they lose their driving skills, said University of Arizona professor Sandra Rosenbloom, an authority on the transportation implications of trends such as an aging population. "As people get older and lose the ability to drive, they narrow and narrow their circle of friends and their circle of activities until it gets to the point where they are housebound and they don't move at all," Rosenbloom said. Public transportation -- buses and trains -- isn't a realistic option for most people who have lost the ability to drive, Rosenbloom said. By the time that happens, the physical and mental conditions that made driving untenable are also likely preclude hiking to a bus stop, especially if there's no bench. The act of getting on and off a bus can be prohibitive. Many older people
-- especially those over 80 -- also worry about losing their balance on a bus and fear being victimized. Marcia Savarese, 73, began driving when she was 16. In 2008, she suffered a stroke and didn't drive for a year. Instead, she depended on friends, expensive taxis and delivery services. Now, she's back on the road despite a loss of some of her peripheral vision. To compensate, she said she's trained herself to turn around to look more than before. She rarely drives at night, and she stays off the interstate. She does much of her grocery shopping and other errands early in the morning when parking lots are nearly empty. Rarely does she drive more than a few miles from home. "I feel it is safer for other people if I stay right in the local area that I know," said Savarese, a widow and retired estate jewelry dealer in Vienna, Va. She didn't want to move from her neighborhood, where she has lived for the past 40 years. "I'm more comfortable here," she said. "My friends are here, my doctors are here, everything is here." ___ Online: National Transportation Safety Board: http://www.ntsb.gov/
