1. Seatbelts are mostly passive, so not a good comparison 2. Same thing with helmets 3. Lawn darts is not a safety mechanism, it's a sport

A closer comparison would be car airbags, but a type of airbag that has false-positives and deploys when the operator drives on a particular type of road surface, in which case the manufacturer calls it "user error" and tells the operator to disable it for that type of road surface. The road surface might appear the same to the operator, so needs to be tested carefully with special equipment before the car is driven on it. And since the active safety system is disabled for this surface, the operator has now paid for a safety system they cannot use, due to manufacturer incompetence
