Looks like Toyota's $0.05 solution to fixing the "sudden acceleration" issue with many of their models, including the 2004-2009 Prius, does not quite fly with the National Highway Traffic Safety Administration (NHTSA). According to a report in Reuters, Toyota is meeting the US government's demands to replace gas pedals in all effected models.

Yesterday Toyota announced an impending recall on all driver's side floor mats for the 2004-2009 Prius. The National Highway Traffic Safety Administration has asked that any Gen 2 Prius owners take out any removable driver's floor mat and not replace it with another mat until Toyota comes up with a remedy.
