'Car-go'

... Or car-do ("the way of the car") :-)
Anyhow - a car is a great and versatile self-defense tool!

Story:
UK -- A shopper has told the Old Bailey how she used her car to scare off a man who attacked a 39-year-old housewife. The man is accused of committing the attack four days before allegedly knifing a teenager in Orpington.

On September 26, the woman noticed a man following the victim in a car park. The woman told the jury she had first seen the man loitering by a car park ticket machine near a shopping center.

When she reached her car on the floor below, she noticed the man was following the other shopper. She then heard screams. The court heard the victim had been knocked to the ground and the attacker was on top of her.

The woman then started sounding the horn of her car and shouting at the man. She told the jury the attacker then stood up and looked at her before slowly walking away. She said: "He stopped doing what he was doing and began to walk away. Initially it was quite slow, which I found quite strange considering what he had just done. He seemed quite cool and calm."

Jurors have already been told the suspect is a loner obsessed with Internet porn, including sites which celebrate rape and other forms of sexual violence. The prosecutor told the court the hospital worker spent hours downloading sick stories and pictures from the Internet.
