Imagine a high-end sports car. It is sleek, shiny, and built to handle the toughest races. On the outside, it looks absolutely perfect. But deep inside the engine, there is a tiny fuel line that has started to rust. Normally, a "check engine" light would flash on the dashboard to warn the driver that something is wrong. However, in this car, someone has placed a thick piece of black tape over the light. The driver keeps pushing the car to its limits, feeling invincible, totally unaware that the engine is struggling. Suddenly - at 100 miles per hour - the engine stalls.
