Car Window Breaker Hammer and Seat Belt Cutter 2-in-1，Emergency Escape Tool | Car Accessories, Auto Car Escape Tool，Safety Hammer for Family Rescue and Auto Traffic Accident Emergency Escape, 2 Packs
A compact tool that clips to a visor or console and has a spring-loaded metal point to shatter a car window plus a hooked blade to cut a stuck seatbelt -- built for the specific scenario of a car sinking in flash-flood water or after an accident where the door won't open and the belt won't release.
Most drivers have never thought about how they'd actually get out of a car sinking in flood water until it happens -- 'car escape tool' isn't a phrase people search preemptively. 788 reviews at 4.8 stars for a $5.99 item shows real, serious adoption, not a novelty purchase.
