Re: 5 year old given rifle as gift, kills 2 year old sister
BUT the main difference is: cars are tools for transportation. Guns are tools for killing. Nothing else. Of course you can use a car as a weapon as well, but you can't use a gun in any other useful way than to threaten and to kill other beings. And there's no single valid reason why a civilian needs such a tool.
I can easily think of a few but one comes to mind the most: hunting. Not everyone wants to buy from stores whether it be high prices, things put in the food, and diseases. (how many times have reports come out just in these last few months of food contamination and recalls) Just because you can't think of a use for a certain tool doesn't mean its useless. An ax maybe useless to you because you can simply turn the natural gas on and heat your home; doesn't mean someone else doesn't need it.
