ok. These things have been discussed on reddit/twitter the last 3-4 years over and over again. Tesla has sold a decent chunk of cars now, from which you can do meaningful projections on it's fire safety.
From Tesla's website (https://www.tesla.com/VehicleSafetyReport) "From 2012 – 2020, there has been approximately one Tesla vehicle fire for every 205 million miles traveled. By comparison, data from the National Fire Protection Association (NFPA) and U.S. Department of Transportation shows that in the United States there is a vehicle fire for every 19 million miles traveled. In order to provide an apt comparison to NFPA data, Tesla’s data set includes instances of vehicle fires caused by structure fires, arson, and other things unrelated to the vehicle, which account for some of the Tesla vehicle fires over this time period."
