A quick back of the envelope calculation shows that, at this rate, the Tesla Model S is roughly 25x more likely to suffer a fire after a collision than a non-Tesla.

While gas powered cars must, out of necessity, carry a tank of flammable liquid around, which is fairly unsafe, the gas tank is not in the front of the car. No other electric car manufacturer puts their batteries so far forward under the hood, either. The Tesla also has very low road clearance.
