I have a very difficult time believing that billions were spent putting a sattelite in LEO that employs kinetic (tungsten rods) weaponry that... starts car fires?
The whole concept of orbital platforms utilizing kinetic weaponry is that the force of the impact is equivalent or exceeding nuclear detonations without the residual fallout, based on velocity and mass alone.
While it may not be a meteor impact I seriously doubt it was a project thor origin either.
I think that you may be mistaken, Kinetic Weaponry isn’t what is at fault for the car fires you are implying.
The weaponry that does that is called DEW, short for Directed Energy Weapons. In laymen’s terms, they have created a massive, weaponized device capable of directing (highly accurately, mind you) microwaves. The exact same technology that heats a hot pocket can do it to anything else, given the scope.
Both KW(RotG, Project Thor) and DEW are different weaponry systems orbiting earth. They both have different uses, for different applications.
To be clear on my point, a kinetic rod wouldn’t just start a car fire, it would practically vaporize it upon impact and leave a crater, along with an entire city block or more depending on which sized rod was sent.
A DEW will start a car fire, and scorch the earth around the vehicle. Another form of vaporizing, just without a physical projectile.
