Let’s say the kid did crawl in the back seat without him noticing….How would he not notice a toddler moving around in the back seat unrestrained while he was driving? Or not hear the kid making noise? Or not have seen her in his rear view mirror in the back seat? My oldest nephew is 3 and believe me even when he’s asleep there’s no mistaking there’s a child in the car.

If this person is this unobservant, they shouldn’t be allowed to be left alone by themselves, let alone drive a motor vehicle.
