For example, I find a broken down Ural truck on the map i scavenge it and i have a chance to get a Truck wheel or a Battery or a Spark plug or maybe multiple parts. Same is applied for car wrecks.
Since non interactive wrecks will spawn no loot and they will be used for environment only, this could be a good way to use them.
I am sure this is in the long term plans, but it would be nice to have sooner than later. Especially with vehicle repair mechanics coming into the equation, these should be part of it.
Really annoying when I need wheels for a truck, and right next to it is another broken down truck with perfect wheels, and even two spare tires.
