cartechboy writes "A Tesla Model S was involved in an accident in Washington state on Tuesday, and the car's battery pack caught fire (with some of it caught on video). The cause of the accident is pretty clear, and Tesla issued a statement that the vehicle hit 'a large metallic object in the middle of the road.' Whether that collision immediately set off a fire in the Model S's battery pack isn't known, but a report from the Regional Fire Authority of Kent, Washington went into detail on the battery pack fire saying the car's lithium-ion battery was on fire when firefighters arrived, and spraying water on it had little effect. Firefighters switched to a dry chemical extinguisher and had to puncture numerous holes into the battery pack to extinguish it completely. Aside from the details of how the battery fire happened and was handled, the big question is what effect it will have on how people view Teslas in the near and middle-term. Is this Tesla's version of 2010's high profile Prius recall issue where pundits and critics took the opportunity to stir fears of the cars new technology?"
