Its not the sound that you want to hear when you get a brand new car delivered to your doorstep. Well not quite literally, but merely hours after Tesla Car #6 was delivered that it met with an accident. Alex Volkov has taken these images seen here at the scene of a Friday evening accident in San Francisco. This is the fourth Tesla to go crashing; the first two crashes were the obligatory safety-related, the third happened when ousted co-founder Martin Eberhard's Tesla rear-ended a truck en route for delivery to Eberhard's home. The cause of this current crash is still unknown but its imperative to note that the Tesla's air-bags never deployed.
