I'm Awesome
Ever see what a piece of porcelain can do to a vehicle's window? A piece off of a broken spark plug, 1/2 the size of a dime, thrown moderately hard, will cause the window to literally explode. Thieves know this. So do the cops. I keep a piece in my console. Just in case I need to help someone that's been in an accident get out of their car. Or to get out of mine.

I had a buddy tell me about this back in the day, but had never seen it.
