I think that's a valid point. Here's a picture of the Toyota distribution center in Portland Oregon-
I don't know the date of the photo but the number of cars has always been like that, long as I can remember. Acres and acres of new cars all brought up the Columbia River via ships just like the one on the left side of the photo. If you're inbound on a flight to PDX on the eastern approach you pass directly over this and several over processing lots. They're always full of cars.
I still think the industries in trouble, just these photos of full lots don't prove much.
