When they interviewed the guy in this runaway Prius, he emphasized that there was nothing wrong with his mat, and the mat wasn't causing the obstruction. He actually bent down and tried pulling the pedal up with his hand while he was going this 90+ down the road. Amazed he didn't wreck then. To try and slow the car down, he said he physically stood up to put as much pressure as he could on the brake. Toyota better give this guy a new car after this experience. I wouldn't want to get back in it. Not to mention, I imagine the braking system is toast, as well as the transmission.
There are believed to be two separate issues. The gas pedal physically sticking on something, and the second, unintended acceleration, just out of no where, the car takes off.
The Camry pedal issue was the floormat/carpet hanging the pedal, then the pedal assembly sticking to itself. The Tundra has a problem with a bushing wearing out in the assembly which causes the pedal to stick.
The unintended acceleration is the big serious issue, which applies to a bunch of cars, Camry, Avalon, ES350, IS250-350 IIRC. The reports/car forums that I've read have pointed to the issue relating to the keyless and go system the cars have (you don't insert a key into an ignition, just push start). At some point during a drive, the system faults. I have no idea why that starting system relates to the throttle going wide open. Maybe at startup, there's a default throttle check, and it just reads wrong and opens the throttle. Or it's tied into cruise control, and cruise opens the throttle. That's what I was eluding to by the cost bit. Toyota would have to reconfigure the way all the systems interact. I don't think just a program reflash would do it.
