That's (yet) another reason why I don't buy the insurance that covers incidents of my own fault for my beater. A crushed bumper will deem it salvage and the insurer will take it away but I could still drive it (and from a relative's experience, at much lower cost than the insurer would pay).

But on a newer vehicle, it takes a lot of damage to get branded salvage.

Also makes sense for Hertz to do it in-house as they'll have a somewhat standardized fleet. Can "borrow" a rear bumper from a vehicle in for more serious heavier-duty front-end repair to get at least 1 back in the fleet.
