writes "Cars already have the technology to determine when you're drowsy, that's nothing new. But having seats with sensors in them monitoring your heart rate to determine if you're falling asleep, that's new, and creepy. A new project from Nottingham Trent University in the UK is working on an electrocardiogram (ECG) built into the driver's seat to detect heart rate and determine when the driver is too fatigued—or worse, falling asleep—in order to improve road safety. The tech uses circuits integrated right into the seats to monitor heart rate, respiration, and more to monitor alertness and health. The idea is the system can take over using active cruise control, lane-keep assist, and other safety technology if the driver were to be drowsy or fall asleep. Of course, the creepy part is the car knows your health and determines whether it would be more fit to drive than you. Maybe in the future you won't get to decide if you're fit to drive, your car will."
