America’s driving population is aging, and GM aims to do something to help older motorists: develop a high-tech windshield that compensates for declining eyesight, the AP reports. The system, now in the research phase, uses lasers and infrared sensors to identify hazards in the road—or perhaps the edge of the road itself in bad weather—and projects them onto the windshield.
Researchers know that sounds distracting to skeptics. "They say, 'That would be very frustrating or confusing, to have things on my windshield. I need to see the world,'" said one scientist. "I'm enhancing the world. I'll take a feature that should be important to you, like the edge of the road, and paint a line over the real edge.” Meanwhile, the 65-and-older population will double in 20 years, and boomers like to drive.
