people who forget their children in the car took proper care, but they fell victim to a cognitive gap that is present in everyone. They didn't do anything improper. If a frozen sewage chunk fell out of an airplane and crushed an infant in it's bed, would you say they parents hadn't taken proper care?Proper care has not been taken when a baby is left inside a car. I would call that the opposite of proper care.
As a society we call it negligence, If someone dies as a result of your negligence you should be held accountable
We're talking about the same thing. It's not a lack of caring or taking proper care. It's a neurological blind spot.
