This is why it's difficult to have debates on TFP. Do people pay attention to what they post? I'll make it crystal clear:
Gun: noun, 1.a weapon consisting of a metal tube, with mechanical attachments, from which projectiles are shot by the force of an explosive; a piece of ordnance.

Car: noun, 1. an automobile. 2. a vehicle running on rails, as a streetcar or railroad car.

So, to make things as clear as possible: a gun is a weapon, and a car is a vehicle. While they can be other things (in addition to their primary role), they are always these things. A gun is never not a weapon and a car is never not a vehicle. A car is only rarely a weapon, therefore suggesting a car is a weapon is completely and totally 100% incorrect and anyone who says otherwise needs to be shut down as hard as possible so there's never any confusion.

I expected a lot more than this from you, Jinn.

Edit: and just to put a bow on my argument, heart disease kills many, MANY, times the amount of people that cars do, so we should probably call the human heart a weapon? Or maybe McDonalds hamburgers? How about high fructose corn syrup, considering that diabetes also kills a lot more than cars.
