Tesla just rejected any notion that its cars are prone to unintended acceleration. In a blog post, the EV maker claimed that a petition describing unexpected acceleration was "completely false" and the product of a "Tesla short-seller" hoping to make a quick buck. Every case where Tesla had a car's data showed that the car worked as intended, the company said. Moreover, Tesla claimed that its system was designed to avoid these problems. All it models have two pedal position sensors, and "any error" defaults to shutting off motor torque. It even uses the Autopilot sensors to catch potential pedal misuse and cut torque to prevent accidents.
