Driving nannies are already starting to get a little ridiculous. If you try to take a turn too quickly, your cars advanced stability control system may automatically apply the brakes and keep you in check. Perhaps the car doesnt think you brake soon enough, so it brakes for you hell, there are even situations where autonomous braking systems have been accused of braking for no reason. What if your car could evaluate your driving skills and determine what youre able to do? What if your car can determine whether or not you drive on the freeway, in snow, or in the rain. What if your car determines how close to the imposed speed limit you can get? Sounds ridiculous, right? Well, Toyota thinks thats the answer to driving safety.
