Sadly the bongs and warnings that are entirely too loud IMO are just there. My biggest pet peeve is the seatbelt warning. Why do I need my seatbelt fastened BEFORE I even power up the car? Why not beep at me if I'm in drive and going faster than ~5-10 mph like most European cars do? That's when you need your seatbelt fastened, so I'm all for an annoying warning if those conditions are met.
The constant loud bongs and chimes honestly make the car feel unnecessarily cheap while not doing anything for safety.
