I am of the opinion that most hot-car deaths are truly a result of distraction, not murder. So, to create a law that would supposedly hinder an intentional murder by hot-car sounds like playing whack-a-mole...these types will easily move on to some other means.
A law like this would do more harm than good--I don't believe someone who accidentally left their child in a hot car should serve jail time.
Oh, my, EIO. If anyone leaves a baby, child or the elderly, unattended until death, inside an enclosed vehicle, wholly on accident, they have unintentionally killed a person. Accidents happen when people are not paying attention to what they are doing. It's equivalent to pointing a gun and shooting it, then claiming you didn't know the gun was loaded when someone is harmed. Ignorance is a poor excuse for a responsible parent and being stupid is not a valid excuse for killing people.
An accident is when you fall off a bicycle and skin your knee. An accident is when a driver wrecks after running a red light and T-Bones another vehicle. An accident is when a tunnel or bridge unexpectedly collapses. Legitimately forgetting and leaving a living breathing person locked inside a vehicle is an accident with consequences.

IMMHO, if adults want children, they are responsible for them until the children are eighteen years old.
For CMJA [Convicted Murderer Jodi Ariass] trial watchers, what is it about a
Cinnabon? Two children were seen left inside a SUV on parking lot video while their Mother goes inside the mall to shop for a
Cinnabon. The mother was not arrested because the PO did not find intent [antonym of accident] and the terrified children were, fortunately, physically unharmed.
