A woman had an accident recently when it was raining. She thought she was being cautious by setting the cruise control and maintaining a safe consistent speed in the rain but her car suddenly began to hydro-plane and fly through the air.
The police attending the accident said that when the cruise control is on and a car begins to hydro-plane on a wet surface the tyres lose contact with the road and the car then accelerates to a higher speed making it take off and go further out of control.
Some vehicles will not allow the cruise control to work when the windshield wipers are on. But not many.
Tell people this and you might save their life.
