It's more like the cashier smacks a peanut out of your hand saying you'll get fat.
Thanks for the hearty laugh :D
Your new car sounds an alarm non-stop if any seat belt in the car is unfastened, whether or not a seat is occupied and whether or not the car is even on. This seems kind of silly, so you raise it with the manufacturer and they say that standard procedure is to just leave all seat belts fastened all the time.
You start doing that and quickly realize that it's much harder to remember to put your seat belt on than it was in your old car, because the car doesn't warn you when you've forgotten your seat belt and when you do remember on your own you have to sit up awkwardly to unfasten it before you can get under it and fasten it around you. You point this out to some fans of the manufacturer and they act like you're the weird one for not seeing how this makes you safer.
But even from an utilitarian perspective, compilers do have warnings and they could just have used that.
If there are multiple people in a car and some choose to wear seatbelts and some choose not to, those who are not wearing seatbelts become a danger to everyone else as their bodies become in-vehicle projectiles.
Sure, I can understand the debate when it's just a single person in a car. But when a person's decision starts impacting others the debate is going to be very hard to win.
Like take the car crash out of the equation and imagine some cars came with an ejector switch that launches you through the windshield at 70 mph. This would not be allowed.
