Toyota's already taken a number of measures to improve the driving of the general population, but it now looks to be taking specific aim at elderly drivers, and it's enlisted the help of a familiar, polygonal face in its efforts. As the AFP reports, Professor Ryuta Kawashima of Brain Age fame is beginning a study in conjunction with Toyota with the goal of creating a vehicle that keeps elderly drivers alert while their driving, which they say could be put into use sometime between 2015 and 2020. That vehicle will apparently be equipped with various devices that "watch the driver's brain activity, automatic nerve reflexes, attentiveness and other mental and physical conditions," according to Kawashima, with it able alert drivers at the slightest sign of danger (not unlike similar systems we've seen aimed at sleepy drivers). We'll just have to wait and see if that'll also involve having drivers shout "red, blue, blue!" at stop lights or not.
