Partly Cloudy with a Chance of Cars

I have a new weather app on my phone. Recently, when I checked its hourly forecast overnight to see if it was going to rain, I saw this:


At first, I couldn't figure out what those little blue cars were doing behind the clouds in the sky. But it slowly dawned on me they probably meant to indicate it was going to be foggy.

I can't be the only one who finds this visual shift from "things located in the sky" to "things on the ground" disorienting. But the idea of little blue cars banging around up in the heavens is kind of appealing in a cartoonish way.
