Greenpeace will tell you that if instead of two cars, if I take the GPS system not from a car, but from a plane and put it in the car, all sorts of bad things are going to happen.  Maybe the car will fly away!  They will tell you the most unbelievable rubbish in order to get you scared.  And what they've done is they've learned very well from the people who make movies in Hollywood.  We know how easy it is to scare people.  People actually love to go to horror movies and watch these movies that get them scared. But usually, you know it's a movie and even though you may be scared for a little while, even a little while after the movie ends, you know that it's just fiction.  Greenpeace never tell you about the fictional aspects of this.  They just want to get you scared.
