These requirements are already a major thorn in my side. My car has sensors to detect when a passenger isn't wearing a seat belt and to blast an ear-hurting alarm directly at the driver. It's so loud that it's actually a safety issue in itself because it's hard to focus on driving when there is a blaring alarm in your face.
The worst of the problem though, is that the system is made to be ultra cautious and thus has a lot of false positives. For example, if I put my backpack on the passenger seat, I have to plug the seat belt in otherwise it will scream at me once my speed hits 10 MPH. Or if one of my kids decides to change seats so unbuckles and moves to a new chair and buckles in that one, then the car will scream at me unless both buckles are buckled, even if there's no weight in the previous seat. It takes several minutes to timeout and stop, meanwhile it is ear-splittingly loud and so bad that it's unsafe to drive while it's blaring.
There are more things, like if I leave the engine running while walking away with the key fob in my pocket, it will loudly honk twice. This happens constantly. Just this morning it honked ear splittingly loud in my face while I was scraping the ice from my windshield.
Then of course there is the complete disabling of the in-car navigation controls while moving, so my passenger can't configure the map while I'm driving, even though there is absolutely no reason to do that. The net result is also that I end up using my phone which is way less safe because I have to look down and the controls are not even remotely optimized for quick and low-attention use.
Our modern way of maximizing the responsiblity of the manufacturer to prevent misuse and minimizing the liability of the person doing the misusing is leading us to some real bad places IMHO.
