Yesterday, a woman driving a 2005 Toyota Prius crashed into a stone wall in Harrison, NY. The Journal News reports that police say "a stuck accelerator pedal 'shot' the vehicle forward. The floor mat had been tied to the seat base with plastic ties and had pretty much been ruled out as the cause of the accident, acting Police Chief Anthony Marraccini said." The woman, who injured her knee, is a housekeeper and was driving her employer's car. The employer said she had driven it many times before, "It was clearly the automobile and not anything else." Just the other day, police in San Diego had to help stop a speeding Prius whose owner says the accelerator was stuck.
