There have been hundreds of such cases and actually quite a lot written on how it is possible that a child could be mistakenly left in a hot car. A practice meant to protect a child, namely placement in a secured seat in the back of the car, puts him/her in danger when a distracted parent, sibling, or other caregiver has no visual cue to unstrap the baby on leaving the car.

"The memory is faced with a challenge when it needs to remember something that you don’t do every day, such as take your child to school,” McDaniel says. For instance, maybe Mom usually does that, but for some reason, Dad takes the task for the day, he says.
“If the child has fallen asleep in their car seat, which is usually behind the driver’s seat, there is no visual information to remind you that there is a kid to drop off and if you have not done it day in and day out, you need a cue,” McDaniel says. “These are not bad parents, but people who don’t have a good understanding of their memory system."

This is a relatively new problem. Prior to the early 1990s, children were routinely placed in the front seat, where it was obvious that they were in the car. In fact, from 1990 to 1992 there were only 11 known deaths of children from heatstroke after being left in a car. After that, car seats were moved to the back. This is when airbags became common and kids riding in the front seat were being killed by them -- 63 in 1995 alone. Not a single child has died due to an airbag since 2003, but at least 110 kids died of heatstroke from 2011 to 2013 -- a tenfold increase over the prior decade. So although kids are safer in cars in one way, they are more at risk in another.
But that isn't the only factor in heatstroke deaths, and safety experts stress that the backseat remains the safest place for children. Another major contributor, one that's more difficult to comprehend, relates to the brain. "These are not negligent parents who have forgotten their kids," says David Diamond, Ph.D., a neuroscientist in the psychology department at the University of South Florida, in Tampa, who has reviewed the details of many hot-car deaths and has spent time with dozens of parents who unintentionally left their child in the car.
Understanding what they did, he says, requires grasping how two very different parts of the brain work. There are the basal ganglia -- the "background system" that controls our habits. "It allows us to do things without thinking about them," Dr. Diamond says. When you're training in sports, for example, you repeat an action over and over to fine-tune your skills. Once it's time to compete, the action is automatic. "Your basal ganglia take over and you don't have to think about how to bounce or shoot the ball."
Then there are the parts of the brain that control new information: the prefrontal cortex and hippocampus. The basal ganglia and prefrontal cortex essentially compete with each other, Dr. Diamond says. When you change up your routine and do something different, then the new details have to be processed by the hippocampus and prefrontal cortex to override the basal ganglia's strong desire to perform actions out of habit.
