Is the wake actually wider in the dry ?
I somehow actually deleted my reply while trying to fix some typos.

The plume would give a fairly good representation of the aero wake, but the water droplets being heavier it is a bit deceptive. The general shape stays the same for the most part, but the weight of the droplets and mist make it fall quicker. In reality the air itself would remain in roughly the same shape, but with the majority staying up higher longer than the mist. I've seen a few photos that people darkened to highlight the flow, and it looks promising for following cars.

ScarbsF1 (I think he changed his social media names actually now) stated in a video that he now expects that it might be common for a following car to line up more "nose to back tire" for reasons of various aero changes. It will be interesting to see if he got it right.
