Yeah that stood out to me too. What the heck is dropping all this stuff? Round here if you put any sizeable metal (like a radiator or something) out front of your house someone will collect it to take for scrap. So if there were that amount of metal on the roads they would be keen to attach magnets to their vans. Although if it needs a large number of high quality magnets to do the job, it might not be economic for them.
