Annoying alarms trigger driver distresss which has equally negative effect on attention while driving.
We had a replacement Yaris that had the speed alarms but one could lower the volume to the point where it didn't matter much. Much better design than the older Toyotas which would beep incessantly and louder if you didn't put belts on, back seats included.
I don't drive/don't have a car, but it drives me mad when I take an Uber, I go into the back seat and put my backpack beside me and the car keeps beeping because of it (I obviously put my seatbelt on). For some time I didn't understand what was that beeping until a driver told me, now when I hear it I know to put the seatbelt in my backpack seat, and remove it when I get off the car.
I ended up buying loose seat belt buckles for my wife's car from a pull and pay to stop this. Evidently nobody at Toyota has a dog.
