The feds and Toyota say the physical evidence indicates what Jim Sikes said happened and what he did on a San Diego County freeway on March 8 don't match, but if you're expecting the California Highway Patrol, which was first on the scene of what Sikes says was an unintended acceleration incident with his 2008 Prius, to make it three for three, stop holding your breath.
The 7-page incident report (which does confirm that Sikes "appeared to be pumping the brakes") refuses to draw conclusions as to whether what Sikes told the CHP was true or not. CHP spokesman Brian Pennings says the agency is not trying to settle the debate and has "no evidence...that will absolutely disprove Mr. Sikes' statement".
Discussion ongoing on the Prius Chat forums.
