The proposal aims to prevent tragic cases of children being forgotten in cars (Child Heatstroke and Death), which occur due to "routine failure"-a cognitive state where the parent's brain is on "autopilot" and skips the crucial step of removing the child from the back seat. Unfortunately, media reports frequently cover such serious tragedies, which stem from various reasons like a sudden change in driving routine, stress, fatigue, or minor distractions, proving that the issue is a human cognitive failure requiring a physical barrier. Existing solutions primarily include passive alerts (like smartphone apps), pressure-based seat sensors, or complex installations that do not fundamentally change the driver's ingrained habit. Existing solutions create "alert fatigue" or allow the driver to easily disable the warning, permitting "autopilot" to continue; additionally, weight sensors tend to be unreliable, expensive, or too complicated for mass implementation. We propose the "Twist-Anchor" system, which utilizes the convenience of the vehicle's Keyless Go technology but requires the driver to change the location of the key fob during every drive. The system is designed to be optional in every vehicle, easy to activate, but difficult to permanently disable (requiring, for example, a mechanic). The vehicle is configured to only start when the key is placed inside a dedicated compartment (Anchor-Zone), roughly the size of a cigarette pack, located in the rear. To start or shut off See more
