content: It could be the human's fault. Driving record is not an indicator, all driving records are perfect until they're not. The woman may have pressed the accelerator on purpose to achieve some goal we aren't privy to -- personal lives stuff. She may have gone for the brake pedal and knew she pressed accelerator on accident. She may have gone for the brake pedal and not realized she pressed the accelerator on accident. Accident or not, she may have a need to blame the car due to perhaps an accumulation of shit between her and her husband where she can't take the blame (even deserved blame) for another accident, at least not right now. She is swearing up and down to her husband that she wasn't at fault. Flip the theoretical relationship status around a bit for a few more possibilities. The husband might suspect, or possibly even "know" she simply hit the accelerator and is denying it. But he has to support her position for some reason, even if it pushes the story into the public. Could be she is hypersensitive to being disbelieved, and she may or may not be a pathological liar. Maybe her entire life is a sham and no one person knows how much she lies. All of this is more likely than a computer mixing up the pedals.
