Feds can't explain runaway Prius

The U.S. government said Monday it cannot explain a reported incident of sudden, high-speed acceleration in a Toyota Prius on a San Diego freeway last week.

The National Highway Traffic Safety Administration said in a statement that it continues to investigate but “we may never know exactly what happened with this car.”

The agency said its engineers are reviewing data from the Prius owned by James Sikes to try to understand what happened with his hybrid. But so far, it says it has not been able to find anything to explain the incident that Sikes reported.
