How many pounds of end-of-life motor vehicles aren't recycled, by year?
Response by poster: A bounty of assumptions follow:
"World vehicle population" seems to be a search term. It looks like there's about 1.4 billion motor vehicles in use today. I'm didn't find how much the average motor vehicle weighs, but it looks like it has been increasing for decades. Something said 2 tons for cars. I assume "motor vehicles" includes everything from motorcycles to the biggest trucks and cargo ships, so maybe that's a decent median? Sounds like 5% not recycled would be a good conservative estimate.
1.4 billion * 2 tons * 5% = 280,000,000,000 lbs of unrecycled motor vehicle waste for all vehicles being driven this year might be within the ballpark? The average car in the US is about 12 years old, so I'll again assume that's a median for all motor vehicles? I groan at the US-centrickness but I also shrug at it because I'm looking for ballparks and the US does have a statistically significant number of the world's motor vehicles. Anyway, so divide by twelve.
23,333,333,333 pounds per year. 25 billion pounds per year. 11,666,666 tons to make it sound small. 800 billion ounces to make it sound big.
I'm still having trouble imagining it. Bored Panda was no help. What does 25 billion pounds of end-of-life motor vehicles (give or take) even look like?

Your numbers seem within reasonableness. I don't have a cite, but I have heard the same 2 ton number for the weight of cars.
I don't know what is meant by "recycled". Does that include "reused" years later. I had a 30+ year old car that every once in a while I needed a part for. My first call was to a local junk yard to see if they had one that I could come scavenge. You need a replacement door latch for a 30 yo car, you buy the entire door from the local yard. When I first started fixing the car up, I purchased a non running one to be used for parts (parts or donor car). The carcass eventually went to a scrap metal guy who likely sold it to a recycling place. But that was years (decades) after the used and useful life of the vehicle.
My gut says that 95% may be recyclable, but way less actually gets processed and recycled. Regardless, the numbers are huge and staggering.
