Toyota's invention of sticking a camera in the dash of a car to monitor the eyelids for dozing off seems pretty smart, even if the concept isn't entirely new. The system would look at your upper and lower eyelids and see whether it's "properly open", which Jalopnik guesses is about 60 to 100% of max. Our question is: would the sensor beep nonstop if an Asian got into the car? Probably not. Seeing as Toyota is Asians, we think they probably took the squinty-factor into account.
AU: looks like the US is a little off the ball here - we covered this on Wednesday. AU rocks!
