The mailbox is the inanimate object more associated with that film, but a mailbox sporting that address floating around in space would have been far too on the nose.
I’m also not sure that Howard Stambler’s truck was distinct enough that the connection to 10 Cloverfield Lane would have registered in viewers’ minds right away.
As J.J. Abrams told The Empire Film Podcast, it might have been too crazy or distracting, but it is hard to argue that such weirdness wouldn’t have been in keeping with the Cloverfield spirit.
The spacewalk was a tense moment in the film, and throwing a bunch of Easter eggs on the screen at that point may have detracted from the weight of it.
