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

You think it’s tricky in cars? Motorbikes have fuel gauges now too.
Essentially [in cars and bikes] they make the gauges slow to react to change so the sloshing averages out to roughly the right amount. This can be seen rather well on a motorbike as the fuel level displayed when you first turn the bike on will be lower [or higher, but usually lower] as the bike has been on the side stand and as you ride off the gauge will catch up to the higher level.
My bike range increases by about 30 miles according to the computer when I get on it.
