According to People's Daily, China, the driver of the luxury car tried desperately to turn off the cruise control but failed. Cruise control allows a vehicle's driver to lock its accelerator at a desired speed and take his or her foot off the pedal.
The driver subsequently realised the vehicle's gear and braking systems had also failed. Panicked, he made a distress call to the police while he sat helplessly inside the out-of-control Mercedes-Benz.
The man's ordeal continued for an hour - reportedly covering 100 kms.
In a particularly close call, the car approached what is usually a busy toll road. But highway patrol sprung into action and managed to clear three lanes of the road just in time to ensure the car could pass through safely.
