Paul Green thinks that automotive design engineers ought to include the elderly in their safety and usability evaluations of telematic devices for navigation and communication. The senior research scientist from the University of Michigan says that older drivers need more time to make driving maneuvers, but the time required for telematics is even greater. "Much larger differences are found responding to warnings, entering data, and reading displays," he says. Studies indicate that 1) drivers aged 65 to 75 years take 40% longer to respond to warnings than drivers 18 to 30; 2) older drivers take 33Ė100% longer to read maps; and 3) older drivers use nearly 80% more time to enter information into a navigation system.
