Not sure if this is why, but pavement is made out of oil.
I also see a lot concrete driveways. Some of the driveways appear to have signs of spalling (chips of concrete popping off). apparently from high heat, while the plastic trashcans nearby are hardly damaged, and the cars nearby have their rims totally melted. I'm guessing the wind directed heat/fire in a certain direction, sparing other things like the greenery, plastic cans, etc., nearby??
