There were two different gas pedals, by two different companies. One works great, the other sticks due to a design flaw. The floor mat situation is different, can can happen in all dbw and cable cars. Its just dumb people that stack 8 or 9 floor mats and trash and such in the floor board and it gets stuck behind the pedal. Its not a software flaw (at least in all except the prius, not sure if that one) its a mechanical.
