Does "800 parking spots per car" pass the sniff test?

There's order of magnitude 1 car per US resident. Does it seem like there are 800 parking spots per US resident? A quarter of a trillion total parking spots?

I doubt my car parks in 800 unique places (including different street parking spots as unique) in a given year.

On the smaller end, call each space 16'x8'. That puts a little more than 2% of the entire land mass of the US as parking spaces (assuming I didn't get any of the exponents wrong).
