I have only ever seen 2 pedals actually hang up during testing.
A 2006 4Runner with 3-4" of floormat material, here's what it had: factory carpet-towel - factory carpet floormat - towel - factory all weather floormat - towel - aftermarket floormat - towel - carpet tile - towel. They were full sized bath towels, too. Really, did ya think it was going to work like factory with all that crap in there??!
Also a 2008 Camry Hybrid. They had aftermarket all-weather floormats that were NOT cut and after 10-15 pedal cycles the floormat caught on the pedal and hung it at 50%. They wanted a NEW CAR because Toyota didn't plan for the aftermarket floormat clearance issue! WTF??!!?! Who comes up with that crap? Really, who? What world did you grow up in?
Yes, I vote stupid, ridiculous recall indeed. /rant
