Whatever it was must have been really important, or else the car must have been stolen...because the damage appears minimal, aside from the engine. I would never have guessed the phone wiring would have been that strong.
One other note: I used to belong to the fire department that responded to this call, when I lived in southwest Houston. Looking up the location of the incident, I would have thought that area would have been annexed by Houston a decade or so ago. The Community VFD (which started out as the Alief VFD) has been seeing its area annexed steadily for years, and I would have thought it would all be gone, certainly everything east of Highway 6, by now.
