You couldn't have the shorted out put applying full power to the motor
like a DC setup, but most of these motor controllers contain reasonably
complex software, and that software could fail in such a way to apply
WOT. The throttle itself could fail in such a way to send 'WOT' to the
controller.... Such a failure would be incredibly rare, but it could happen.
