Sudden Tesla acceleration attributed to voltage spikes that may have tricked NHTSA into ruling it driver error

Researchers may have found the culprit behind the sudden unintended acceleration problem that Tesla vehicles have often been accused of. While investigations by NHTSA and Tesla attributed it to acceleration pedal mishaps, invertor voltage spikes may have mimicked erratic driver behaviour.

Disclaimer, I am no engineer but why wouldn't you build in a check position of accelerator pedal to the condition handling logic? What possible reason could there be other than incompetence, expedience or negligence?
