Another accident or fire, not sure just happened

By the time you get stopped from 60 mph assuming you noticed the smoke early on from a engine fire... you will have a raging fire. I carry four fire extinguishers and doubt that they would get it all out. Hard to tell the source of the fire and if it was a engine, I would think all of the rear cap would be gone.

I can see the three louvers of the lower vent for a NoCold refer so for once it's not the source.
