The automobile industry is so entrenched in our society that recycling of automotive materials is a very mature industry. One reason lead-acid batteries are attractive for electric cars (despite flaws) is that the recycling infrastructure for such batteries is already there. Same for steel, tires, wiring, and other things, which all have in-place recycling systems that get as much reuse as possible out of these materials. When I buy things like tires, I pay a recycle charge for my old ones. The technology for this is always improving--it saves the auto industry money when the stuff comes back around again.

Our industrial society used to use almost as much of a wrecked automobile as the old Plains Indians used of a buffalo. I don't know what the situation is for modern plastic components, which are more difficult to recycle than metals, but not impossible.
