Pedal, not petal.

Not trying to be an asshole, just a nudge to avoid misunderstandings (although the context is clear in this case)

I realize it's the pedal that gets stuck, but the computer registers the state of the pedal via a sensor.

The computer should be smart enough to realize something ain't right when it registers that both the accelerator and brake pedals are being pressed at the same time. And in that case, the brake should always take priority.
