How do cars measure fuel level accurately when the fluid is constantly sloshing around?

They can’t. They do their best, but it will *still* shosh around.
Pretty sure that onboard computers tend to do an *estimate* based on the last readings, and on your current mean fuel consumption, which they then recompute periodically, maybe using the mean of the fuel readings. Like, if it oscillates between 12 and 8%, it must be around 10%
Also, when the level gets too low, you usually have a “reserve” reading, instead of anything more precise, because they’re not able to gauge how much is left, only that it’s not a lot.
