New details are emerging from a federal investigation into the crash of a runaway Lexus ES 350 that killed off-duty California Highway Patrol Officer Mark Saylor and three members of his family. The LA Times reports, citing documents from the National Highway Traffic Safety Administration, that the Lexus had improper floor mats from a different model, and that the gas pedal's design could make it more susceptible to obstruction. The car's brakes were also found to reflect the driver's attempts to slow the vehicle down during its high-speed run.

The NHTSA report reads, "Rotors were discolored and heated, had very rough surfaces, had substantial deposits of brake pad material, and showed signs of bright orange oxidation on the cooling fins consistent with endured braking." [Details]
