GPS is becoming an important element of our daily life. People use it to get to their final destination as it replaces the paper maps that drivers used to rely on. It is also used in many life areas. Sometimes, it can end up with unknown results.

After that time GPS use has dramatically changed in a way that nobody had predicted it.
