It’s for when you have people or stuff in the back, so the car squats a little. I think it’s mandatory over here in Europe, at least I’ve never seen a car without it.
Auto leveling is also mandatory for headlights above a certain limit, at least in my country (not sure about LEDs, but e.g. my car has xenon headlights that are weaker on purpose, because if they were any brighter, they’d have to be able to auto-level and have a cleaning system).
