A freak accident on the streets of San Francisco has left two cars awesomely mangled, one driver under investigation, and thankfully, nobody injured. Driver Ricardo Perez was piloting his 65 ton crane down Nevada street in the famously hilly berg when his brakes unexpectedly gave up the ghost. Faced with the choice of going out of control or finding an alternate slowing solution, Perez decided the best course of action would be to use a row of cars as brakes and plowed through the line of parked cars, damaging three and leaving the utter carnage of two you see here.
