group by cause of fire. To simply say an ICE vehicle had a fire implies it had an origin with the gas/diesel engine. It does not account for fires that were electrical in origin. It also does not account for ICE vehicles which were "performance modified" by their owners. Owners swapping out parts for "aftermarket" the fuel delivery/electrical systems is very common. Problems and malfunctions with aftermarket parts is likewise very common.
However the numbers shake out I expect an EV to still have fewer fires but I don't go for arriving at a conclusion on misleading application and analysis which is what most of these "studies" do. The NHTSA accident reporting data is and has been seriously flawed for decades with unequal application of criteria by safety responders and misreporting of items. Many times forms are half filled in at best. We suffer from this in the trucking industry because even if a car crosses the median and strikes a semi truck it still is considered a "truck involved" accident and counts in total figures and is cited by "safety" groups as an indication of severity of "problems" with safety in the trucking industry. We have for decades been demanding more accurate recording of circumstances and facts surrounding crashes in order to better analyze the situations presented and formulate responses to focus on crash avoidance/reduction of severity based on accurate information. We haven't gotten much from the Feds other than "we'll take your suggestions under advisement" sorts of answers.
So how accurately do these "fire" statistics cited reflect what's really happening? The answer is we don't know at this point but we know from past experience not to rely too heavily on accuracy for either ICE or EV reports.
