Toyota Motor and a Toyota affiliate has developed an image-processing computer system uses a camera near the steering wheel to detect when the driver stops looking straight ahead, USA Today reports. The system flashes a light on the dashboard display and beeps when the eyes start to wander. If the driver still doesn't respond, brakes kick in, Toyota said. According to USA Today, the feature will be offered in Lexus luxury models set to be sold in Japan next year. Toyota won't comment on whether it will be offered in models sold abroad, company spokeswoman Keiko Nakajima said.
