Oh no, I did the math. Just the Chesterfield Mall lot that they mention with 500 cars, 1% of their overstock, is ~48k sqft of bumper-to-bumper cars if using Tesla '24 dimensions. This puts just that lot on the low end of human visibility from the International Space Station.

(If you were to somehow get all of their overstock from the last year in one location, it would cover a large enough area to write a human-readable message of "Hello" from the ISS using them.)

Oh, I see. The criterion is "visible to the unaided human eye from orbit". I concede the point.
