As seen in the movie "Land of Nomads". Sometimes you find yourself in an apartment where nobody comes and saves you. That and the ability to follow simple instructions (included) can mean a roadside rescue. The best breakdown insurance for on the road: these tools and a DC tire inflator (cigarette lighter). Especially now, when there is no room for a full-fledged spare wheel in cars. And using Goo can affect the TPMS sensors and/or render the tire beyond repair (I'm afraid I heard it. Don't worry, it must be evil). Better to have and not need than to need and not have.
