On a hot day a car can act like a green house. It can heat up by 20 degrees in just minutes. That makes leaving a child in a car can turn deadly.
In fact, the National Safety Council says that 742 children died of heat stroke in vehicles between 1998 and 2017. On average, 37 children die each year after being left alone in hot cars.
Several companies want to help remind rushed and preoccupied parents to check their back seat.
General Motors has a "rear seat reminder" built into more than 20 of its 2017 and 2018 models.
The rear seat reminder will flash a message on your front controls and ding five times if the back door is opened and closed up to 10 minutes before the car starts.
The navigation app Waze has come out with a similar function. The Child Reminder setting will alert you to check the back seat
once you've reached your programmed destination.
