I thought the same thing. I read of the thousands of ICE vehicle fires each year and wonder (not really) why we don't have an outbreak of articles every time that happens. But, let one Tesla hit a brick wall at 100 miles an hour and catch fire 20 minutes later, and it is a major news story that won't die for weeks.
Tesla has very little to do with Lithium Fires. You can blame it entirely on General Motors.
The EV battery fire craze started with a 2011 Chevrolet Volt when the NHTSA did the side pole ramming test in spring 2011, and the car got 5 stars for the crash. Then without doing the marked Emergency Responder Crash protocol (unplug the orange DISCONNECT plug or 3 other ways), and parked outside in the rain for weeks, it finally caught fire nearly a month later due to one of 3 causes: Bus cable shorting from coolant, damaged cell thermal runaway, or arson (unlikely). Ineptitude by the NHTSA techs was not considered a factor.
So the General Motors got the most stringent tests ever done by the NHTSA on a 'no-reported incident' vehicle. In an unprecedented move, they evaluated fire potential with zero fires reported in the wild. (Later two arsons would claim a wild pair). They tried to get 6 batteries to catch fire by destroying just the battery, and did get 2 to ignite by flipping them upside down after puncturing them.
There seemed to be no more cause for concern than any battery you try to immolate. In fact, there might not another EV battery in existence that is harder to ignite than a 2011 Volt battery. Done, right? No, this is the Evil Car Company, they MUST be fvck-ups, and we will PROVE it.
SO,,, The NHTSA was sort of pissed. Could not get the Volt to reliably catch fire even if they tried hard with just a battery. So in November that year, they tried again. No dice.
I do praise the NHTSA for calling it quits when they wasted millions and did not get the results they wanted. If it was perhaps CARB or NBC they would have just poured magnesium powder on top and put a squib in it. EDIT - NBC used Estes rocket motors, drilled .125" holes in the tank, used a radio controlled ignitor, and 3? trucks to pull it off. They later hid the trucks and removed the VINs, but they were found.
(Footnote: GM improved the armor twice since the original 'no-incident' month delayed fire)
Historical footnote, staff on Dateline were paid by lawyers of plaintiffs before the episode. Later a university and the NHTSA both validated GM's claim that the fire rate on the GM trucks was no higher than Ford or Dodge, at all. A complete and utter fabrication from the start.
