The following shows how electromagnetic radiation can be injected into the circuitry to cause sudden unintended acceleration. When this occurs the brakes will not respond, just like Teslas "brake failure" issue. Realize that when this occurs in a Tesla, the EDR will record accelerator pressure until the computer cycles, despite the driver hitting the brake.


ECREATING THE “STUCK THROTTLE” PROBLEM ON A TOYOTA

most manufacturers have switched to a fly-by-wire system which takes sensor input from the accelerator pedal and sends that position information to the vehicle’s computer which in turn adjusts the throttle position. This might be slightly cheaper to manufacture, but introduces a much larger number of failure modes to a critical system.

Colin] is recreating one of those failure modes by introducing an electromagnetic pulse at a specific point on the vehicle’s computer. In the real world, this could be caused by certain forms of EMF potentially including cosmic rays. This introduces a memory fault which the computer doesn’t seem capable of recognizing or clearing. With the right set of circumstances that [Colin] can reliably produce, the computer eventually will drive the throttle fully open, and the condition can only be corrected by power-cycling the vehicle’s computer.

This is whats essentially happening in all those Teslas that are suddenly accelerating!

Good photo of the Teslas that caught fire after it hit a curb(?). Looks like the rear engine is on fire as the fire was too easy to put out to be the batteries. Despite the driver being impaired, it looks as if a short in the rear of the car caused the driver to lose control and subsequent fire.

Police say the driver lost control of the vehicle and it collided with the curb.
