That's not pine dust... it's pot pollen. Says so right on that windshield.
There are handfuls of conifer down here in the El Lay basin... and each spring, late, we too get our cars dusted, although not nearly as bad as you have it, being there in the thick of things as you are.
And just a few months ago, every single parking lot (where one could actually notice this) was covered in a fine layer of brown silt. Couldn't keep any car clean for longer than 10 minutes. Silt the result of brushfire/wildfire ash, then blown topsoil. I'd never seen it that bad.
Ah, the things we notice once we're a little older, have been around the block more than once and when we try to take care of our vehicular inve$tment$.
