Where does Clark Kent make his transformation into Superman these days?

And where are the clothes while Superman it being all…super?

I’ve not seen a modern Superman movie, so I don’t know if the absence of phone booths has been addressed, or not. Surely.

I could Google it, but I’m hoping this approach will be as informative and more entertaining.

If I were charged with solving the problem of missing phone booths, I’d probably have Clark remove his suit coat and walk to a secluded area where he throws the coat over his back and leaps into the air, where his suit morphs into his super tights. Land, remove the cape, reverse.
