That is not the worst case scenario. Dangerous acceleration, braking, steering, or some combination of the three are far, far worse. I've repeatedly had lane-keeping veer off-road while adapative cruise control accelerated at the same time. That's incredibly dangerous and if I hadn't had my hands on the wheel and my foot resting on the brake pedal I may have driven into a tree/sign/parked car. I don't use lane-keeping anymore. Slowing down until stopped with some emergency lights on is also plenty dangerous if it happens on a high-speed road.
