REAL WORLD SPOOFING

Is GPS spoofing even dangerous? What's the worst that can happen?

GNSS signals are unencrypted; therefore, anyone can manipulate them, and since the signals have to travel far from satellites in space to receivers on earth, they become weak and easy to harm.

A spoofing attack can slowly divert a vehicles 'virtual' location, creating a dangerous situation in which the vehicle physically drives the wrong road by manipulating the perceived location. 

In the video, we can see a car drive on a straight path that later forks into two different lanes. Although the actual car drives in the left lane, the car's location on its navigation system is diverted to the right lane.
