We need visibility in order to maneuver our vehicles, don’t we? A light coat of oil from a bug sprayer and a balloon full of flour will bring it to a halt. A few cans of spray paint will work even better.
Only use the bleach and ammonia bottles if there is shooting going on.
Armored vehicles aren't working that great in the 3rd world, circa 1850s technology, they certainly aren't going to work in the first world with folks that make that kind of stuff for a living.

Technically, no... I've done driving by braille before. If you don't like the way I drive, get off the sidewalk. ;)
