If your area has a lot of car fires I'd be interested in where they all were serviced. I worked at a service station for 3 years and a Ford dealer for 42 years, the only car I saw burn in that time was a mid 80's LTD that had just driven from the independent garage who'd been "fixing" it for a week. It was running so rich the cat overheated and caught the carpet on fire. The was a recall once on Ford ignition switches that could arc and cause a fire, we changed hundreds of them and never saw one that looked like it had gotten hot. Teslas seem to spontaneously combust but that gets downplayed by the media, almost like Toyota recalls: Tacomas and Tundras have frame replacement recalls that have never been covered by the national news and the company blamed their unintended acceleration on their customers being too dumb to pull the floor mats out from under the gas pedal.
