El Cajon – Investigators say it is now possible that the floor mats had nothing to do with the car crash that killed the Saylor family. “It could be the floor mats. It could be the pedals. Or it could be the algorithms,” or how the vehicle handles faulty signals from its sensors, Folck said. “It’s just hard to know what it is.” A forensic mechanic who reconstructs accidents and vehicle defects for a living, Folck says the crash could well have been caused by a floor mat — just as the National Highway Traffic Safety Administration concluded. The bottom line is investigators still are not sure and Toyota might have jumped the gun with concluding that it was only the floor mats. So far Toyota has recalled 5.4 million vehicles for floor mat problems and 2.3 million vehicles for sticking accelerator pedals. Toyota has maintained that it has not identified any problems with electronics in its vehicles that could trigger the sudden acceleration, and no outside body has proven such a fault exists.
