DETROIT (Reuters) - Assisted driving systems installed in Tesla Inc, Hyundai Motor Co and Subaru Corp vehicles failed to avoid head-on collisions in testing done by AAA, though Tesla's Autopilot system did slow the vehicle to a walking speed before striking an oncoming, foam model of a car.

The AAA, a U.S. consumer and travel services organization, said the tests illustrate how current assisted driving and automated braking systems fall short of true autonomous driving, and require drivers to stay in control of vehicles.
