The poster also asked what people really keep in their cars and homes beyond the usual advice to store water, a radio, and a first aid kit.One commenter wrote: "Ductape, in case you have issues with a window. Add a heavy-duty trash bag, in case you really have issues with a window."They also advised checking ahead of time whether the tape will actually stick to the car body, the window, and the bag, rather than finding out during an emergency.Other commenters suggested adding items such as a battery jump starter, tire inflator, ponchos, blankets, warm socks, headlamps, windshield washer concentrate, warning triangles, and extra high-visibility vests for passengers.More backgroundMany drivers keep some kind of emergency kit in the car, but few inspect it often enough to catch missing items, dead batteries, expired supplies, or gear that has drifted back into the house.One commenter posted a highly detailed list for both a vehicle kit and a separate "SHTF" bag, including water, a radio, first-aid supplies, power banks, maps, and protective gear. The same commenter noted, "these things are very individual based on circumstances, capabilities and risk."What makes sense to carry also depends on where you live and how you travel.People in colder areas mentioned snow shovels, old carpet, and saws for storm debris, while another driver with a two-hour commute said they keep food, boots, a coat, and a blanket in the car and later said they had once waited eight hours for recovery.What can be done?Start by taking everything out, checking what still works, and repacking it into one dedicated place.A hard case or bag doesn't help much if the contents are incomplete or hard to reach.Keeping the kit maintained matters as much as owning it.Charge battery packs, rotate water, replace expired medical supplies, and test adhesives, lights, and pumps before you need them.For people who spend long periods on the road, a few comfort items can also make a big difference — snacks, blankets, ponchos, or even something to keep passengers occupied during a long wait.Where can I learn more?A neglected car kit is one good reminder to take stock of your basics.
