If passed, all cars would be required to have the warnings.
Members of the US House of Representatives have submitted new legislation proposals that, if passed, would force automakers to equip all new cars with an alert system to prevent parents from leaving children unattended in cars.
The bill, cleverly called the Helping Overcome Trauma for Children Alone in Rear Seats Act of 2016, abbreviated as the HOT CARS Act, has been introduced by representatives from Ohio, New York, and Illinois.
The goal is to prevent inattentive or careless parents from leaving kids and pets in cars. As Jalopnik points out, an average of 37 children die from heat stroke each year as a result of being left alone in vehicles, according to safety advocate group KidsAndCars.org.
The exact type of alert wasn't specified, with wording in the bill simply requiring that "all new passenger motor vehicles be equipped with technology to provide an alert that a child or unattended passenger remains in a rear seating position after the vehicle motor is deactivated."
The same article points out that manufacturers such as General Motors are already enacting warnings that would seem to fall into this category. For example, the 2017 Acadia models is already slated to come with an audible chime and written reminders.
