Good point, I’ll bet if the damn government never came up with that law several children who are now dead would be alive today. Government knows best huh. But how tired would you have to be to forget your own baby is with you in the car?!
Familiarity breeds contempt. There are electronic devices that beep once the parent and the child are separated by some distance. It is wise to use them.
Humans are known to make mistakes; machines help us detect and prevent those mistakes. They will not guarantee safety and security, of course - nothing does; but they improve your chances.
It seems like it could not happen. That would just about kill a person. I hope the State Does punish her in some way, it may keep her alive.
