I am another one of those guys who was opening my eyes wide open reading this thread!!!
I do not have any tool in my '57 Suburban, or in any of my cars, for that matter. My '93 Buick has not had s apare wheel for years! If my wife is with me, I can use her cell phone. And if you are really scared, get a AAA membership, for convenient free tows. Or buy a new car!
Tools are dead weight and they make rattling noises all the time, too.
