Yes, ease does not come easy. But this does give the appearance of ease. As you say, strangeness and complexity are just two possible virtues of a poem, and they have their limits. I simply found your limpidity here, if you will, worth pointing out. The text appears to go down easy, which can mean quickly.
I think this line - "most assuredly/he will be crashing" - would seem less odd to me if it concluded "... driving for the next five hours."
I see what you mean about the floating modifier. Smidge I think I just don't much like, as a word - it's always felt coy to me. Smudge, not so.
