There has to be intent you fricktard.
Pretty common sense, even if the stupidest persson in the world (looking at you minorities) leave their child in a hot car and let them die it's not an accident.
How though whenever another living creature is left in the car they are all of a sudden forgetable?
I forget my inside lamp is on. I forget my cellphone is in the car.
Pretty hard to fricking forget that animal or child that depends on you isn't around for the rest of the night.
