14k kilometres, breakdowns, sandstorms, extreme isolation.
Just imagine being in your car in the middle of the desert, thousands of kilometers away from the civilization, and the car breaks down. Painful. Or maybe not so much. You can either fix the car, or not. If not, then you have to call someone to save you. Hopefully you have enough food and drink until the help arrives, and hopefully you survive the climate of the desert.
This is a little scary/frightening to think about.
