The report also quoted the American Academy of Pediatrics as saying that heat stroke is "the main cause of death of non-crash vehicles for children under 15 years of age." According to reports, the number began to rise when parents were advised to move the car seat to the back row (to avoid the equally dangerous force of deploying airbags).
But automakers are trying to take action on it. In 2016, GM introduced the Rear Seat Reminder rear seat reminder system, which can determine whether the rear door is opened before the vehicle departs, reminding the owner to check the rear seat at the end of the trip. The system will soon be standard on all four-door vehicles, including cars and SUVs. Nissan's Rear Door Alert feature alerts almost in the same way.
However, these are not everyone's solutions - at least not yet. As Brian Cooley's 2017 report points out, this feature is usually found in new cars, such as an average transaction price of at least $35,000, which ignores low-income families and individuals. According to the latest data from the Traffic Statistics Bureau, the average age of all cars on the US road is 11.6 years.
