Could be onto something. Just leaving metal box tubing alone will be picked up in a day. It got to the point, that my recycling bin was emptied of all beer cans. Made me think that it was time to cut back. The problem thought I can see is that if a car is slowly left out there in chunks or on craigslist, that it might not be viewed as the most legal way to get a car off your property. I'm not sure if anyone has contacted local enforcement to see what is the approved way to do it.
