But what I came back to say is: Bubbles!
They can be generated at ambient temperature and I think they can be tuned for persistence. A multiple exposure of 1 bubble/second would be a low-resolution sampled average, or you could track single bubbles with a high frame rate—60 frames /second would be every 1 1/2 feet at 88fps/60mph.
Foam streamers. The mind boggles.

Didn't Mercedes do some studies with bubbles filled with hydrogen,to get really low inertia and neutral buoyancy?
