Earlier this week, technicians from the NHTSA and Toyota reported that after thoroughly examining Sikes' car they could find no forensic evidence that the brakes and gas pedal were deployed simultaneously:
Toyota has said all Priuses are equipped with a computer system that cuts power to the wheels if the brake and gas pedals are depressed at the same time, as Sikes was doing.
"It's tough for us to say if we're skeptical. I'm mystified in how it could happen with the brake override system," Don Esmond, senior vice president of automotive operations for Toyota Motor Sales, said Thursday.
A Toyota official who was at the inspection explained that
an electric motor would "completely seize" if a system to shut off the gas when the brake is pressed fails, and there was no evidence to support that happened, according to the memo.
"In this case, knowing that we are able to push the car around the shop, it does not appear to be feasibly possible, both electronically and mechanically that his gas pedal was stuck to the floor and he was slamming on the brake at the same time," according to the report for the House Committee on Oversight and Government Reform.
A day after the Sikes incident in California,
another Prius driver blamed a vehicle crash on a stuck accelerator. A Harrison, NY resident claimed that as she was easing out of her driveway the accelerator on her 2005 Prius suddenly jammed. The brakes on the vehicle also failed, causing her to accelerate out of control and crash into a stone wall. But after technicians from the NHTSA and Toyota examined the car, they firmly concluded that "the car's event data recorder 'indicated there was no application of the brakes and the throttle was fully open.'"
As new "unintended acceleration" reports make news headlines, we continually find out more about the impressive number of safety features that Toyota included in the mechanical and computer systems of the Prius. Of course gremlins can pop up in mechanical systems at any time, but these latest reports of unintended acceleration by Toyota vehicles seem far more likely to have involved errors in human judgment rather than mechanical failure.
