That's how many parking spaces there are in the USA. For every car? About 4 empty spaces... just sitting there, not absorbing the rain, making flooding worse, making cities hotter as they bake in the summer sun.
Our built environment and laws bend over backwards to make driving the only viable transportation option in nearly every imaginable context.
You need to pay for healthcare, but almost never parking.
(Pointing this out makes libertarian heads explode.)
