These depend heavily on car. What kind of car is this?

The decision to have an annoying beep instead of a soft ding or pop up is stupid but many cars do this. Mine handles seatbelts well and never has a false positive there so it's not a general modern car problem (2021 sonata).

Nice, that's good to know. It's a 2023 Toyota Sienna, and historically Toyota has been the most sensible of cars I've driven (much, much better than Ford). I'm overall pretty pleased with it, minus a few rough edges like mentioned. I'm really glad to hear that it's not a widespread industry issue though.
