Anti car speaker system
Ever hate those annoying folks who drive by your house with their bass system shaking your windows, walls, and floor? Waking up your children, preventing you from studying? The government has laws about regulating noise in residential areas but rarely enforced. What better way to enforce these laws with an EMP gun turret.
Mount this bad boy on a telephone pole in a residential area. When a driver passes by with audio levels prohibited in neighborhoods, the turret locks onto the car and fires an EMP blast. This will disable the car, the stupid car stereo, and anything else electrical.
