I'm guessing the driver's seatbelt ding is one of the mandatory ones. Thanks to the 99% of terrible drivers in the US and our incompetent regulators, we get enforced mandatory enshittification.

Enshittification would be something like selling third-party access to drivers eyeballs in a way that fucks up the infotainment UX, or selling driver data in a scummy way that encourages phishing attacks from within the infotainment screen.
Not sure how it would actually continue from there, but eventually this process of screwing up the end product in the interest of rent-seeking would make it difficult for the person to actually drive from point and to point b, which is the whole purpose the car was designed for. And at that point people would start questioning Kia (or whatever) as an actual vehicle useful for transportation, and the company would then fail.
That would be enshittification. What you describe is just an annoying safety feature.
Even if the regulations require a ding for any speed, I assume it doesn’t need to ding when in park.
