The video covers the multiple options that a driver has if they feel their Toyota hybrid is accelerating without their input, including the brake override function, how to shift into neutral and the last option of shutting the vehicle off entirely.

As the video points out, Toyota's hybrid models feature a brake override system, unlike the rest of its current lineup. This feature, if functioning as intended, should override the accelerator in the event that the brakes and accelerator are applied at the same time. When the computer receives both a braking and acceleration signal simultaneously for more than one second, the engine will stop accelerating and return the engine to an idle position.
This video demonstrates that the recent incident in San Diego was either the result of abnormal function of the vehicle's computer, or complete operator error on the part of the driver, James Sikes.
