The greater amount of energy that a battery stores creates a greater fire hazard.
The battery pack is 85 KWh, or equivalent to roughly 290,000 BTU's of energy. 1 gallon of gas is 114,000 BTU's of energy. So unless you drive with less than 3 gallons in your gas tank, your assertion is incorrect. Also, the battery pack electrolyte is flammable, but not explosive. And the car has a firewall that has prevented any fire intrusion into the cabins of the 3 cars that have caught fire. In the case of that picture, only the front of the car burned, after the driver took part of a semi trailer through the battery pack. The fire fighters inadvertently made the fire worse by cutting through the firewalls of adjoining battery packs, allowing them to experience thermal runaway and catch fire, before it was finally extinguished. It took roughly 20-30 minutes for the front of the car to burn. Cant say the same for ruptured fuel lines or tanks.
