There is no doubt that human ingenuity has helped us in many ways but unfortunately, it is also used for the wrong reasons as well. For example, it is common in some areas for thieves to roam around and look for ways to break into your car. They can either steal things out of your car or if they know how, they can steal the car itself!
One of the ways that they have been breaking into cars recently is by putting a penny or nickel in the door handle. It keeps you from fully locking the doors, so they can just come behind you and get into your car easily.
