My girlfriend was driving on the free way and had her cruise control on. I was behind her following her. The next thing I know her car speeds up and starts flying. I thought she had gone crazy. I tried to keep up with her and she was going at least 90 then started swerving back and fourth. Turned out the cruise control not only got stuck on but the car kept accelerating. What in the world kind of malfunction causes that? By the way she is fine after a few minutes the breaks finally stopped the cruise control and she was able to get off the road.
