My car spontaneously burst into flames after I parked it. I had left the car parked and locked in a parking lot next to a rental house and went in to prepare dinner. 20 minutes later my friends arrived at the scene and alerted us to the fact that my car was engulfed in flames. It seems that the fire originated in the engine somehow, but exactly what started it is unclear. There was no accident or collision, and no foul play. Security cameras in the area couldn't see much, but indicate that the vehicle burst into flames pretty much just after I had left it parked and locked.
