Automakers Can End Hot Car Child Deaths -- And Lawmakers Should Lead The Way

Their stories are heart-wrenching. In October, a Phoenix school administrator left his 4-month-old daughter in the back seat of his car all day. In August, a New Jersey commuter left a 22-month-old girl in a minivan parked at a railroad station. In July, a New York hospital worker left his 1-year-old twins in his car while he went to work. Tragically, all of these children succumbed to heatstroke. Since 1990, this tragedy has replayed more than 900 times, as overstressed, overtired or distracted parents and caregivers left infants and toddlers alone in locked cars while temperatures inside rose relentlessly. During 2019, 52 children have lost their lives this way. Now automakers have announced a commitment to building alerts into all new cars to warn drivers against leaving anyone in the vehicle. But child safety advocates believe alerts alone will fall short because they sound every time drivers exit vehicles, whether the back seat is occupied or vacant. Eventually, such alerts become too familiar, and we tune them out. The proposed voluntary measures fall short of what’s truly needed: detection technology. Strong legislation like the Hot Cars Act would mandate systems that detect people and pets in the car and set off alerts only when they’re needed. With too many sad news stories burned into memory, a tough new law is, without a doubt, the best -- and only -- answer. Misunderstanding Memory Nonprofit notes that hot car deaths are misunderstood because they happen to “the most loving, caring and protective parents.” Founder Janette Fennell says, “When you’re saying, ‘This could never happen to me,’ you’re saying ‘I’m not human.’ This is just how our brains work.” In a neurobiological and cognitive phenomenon, our brains pit habit memory against prospective memory. The first governs predictable, oft-repeated actions, like driving to work every day. The second involves planning future actions, like dropping off a child at day care when it’s not your usual routine. Habit memory easily dominates prospective memory, especially when coupled with sleep deprivation, distractions, stress and multitasking -- the stuff of everyday life. Never assume this tragedy couldn’t happen to you, neuroscientist David Diamond writes in the article linked above. “The evidence is clear that this assumption is wrong.”

Prevention Is PossibleLook before you lock” tips offer simple steps to help counteract habit memory: Leave something essential, such as your laptop or wallet, in the back seat; open the back door every time you park; ask childcare providers to call immediately if your child is late. But technology promises the ultimate solution. That’s why international trade groups recently announced plans to install electronic alerts to help stop heatstroke deaths. And participating manufacturers promise to add rear-occupant alert systems to nearly every 2025 model vehicle in the U.S. Major U.S. automakers already install detection and alert systems or plan to offer them soon, including the following:

  • Ford will begin offering a rear occupant alert system in its model year 2020 vehicles, using ignition and open-door switches to alert drivers.
  • GM offers a reminder system with sensors in the doors that activate if the rear doors are opened after starting the car or while it’s running. When the car stops, a dashboard reminder appears, and chimes sound.
  • Hyundai and Kia use ultrasonic motion detection and rear-door logic in their systems. Rear doors opened before or during a trip trigger a dashboard warning, chimes and honking when the ignition is turned off.
  • Nissan uses door sequencing to monitor rear doors. If doors are opened at the start of a trip but not after the engine stops, the reminder system displays a warning on the instrument panel and sounds the horn.

Manufacturers can also install sensor technology developed by a number of tech providers. My company is among these solution providers, and mentions us in their company list linked above. Other providers include the following:

  • Caaresys BabyCaare uses contactless, low-emission radio frequency radar to detect vehicle occupants, note their positions and monitor vital signs. When a passenger is at risk, it honks the horn, flashes the lights and pushes notifications to smartphones.
  • OleaVision Sensor Networks detect vital signs and can send alerts to smartphones if any passenger is left behind in a vehicle.
  • VitaSense detects occupants, including newborns, based on their movements or breathing, even when they’re sleeping. Low-power radio frequency technology provides this information to the vehicle’s warning systems.

In addition, car seat alerts and mobile apps are available to consumers, including the following:

  • The Backseat App for iPhone and Android reminds drivers to check the back seat after parking, and sends email and text messages to predetermined contacts if there’s a chance a child has been left behind.
  • Cybex Sirona M SensorSafe Car Seat integrates a sensor into a safety harness chest clip. When a driver leaves the vehicle, they’re reminded that there’s a baby in the car seat. Smartphone notifications are sent if the child is left alone.
  • Driver’s Little Helper provides a sensor that’s tucked under the car seat padding and synced with an app that sends smartphone notifications after the car stops.
  • The Kars 4 Kids Safety App for Android connects to the vehicle’s Bluetooth system and sets off a smartphone alarm when the driver leaves the car.
  • The Waze Child Reminder setting prompts drivers to check the back seat when they arrive at the destination entered into the app.

For carmakers and lawmakers alike, the road is clear. If they truly want to solve this problem, then committing to detection systems is a no-brainer. Whether they're mandating the inclusion of sensor technology or encouraging the use of applications and alerts -- ideally both -- one thing is certain: We need to do more to stop these deaths.
