I have been watching some dash cam videos on YouTube, why is it that in most of the accidents the Windscreen wipers activate on impact?

    It's an automatic system that is only meant to activate when you hit a pedestrian. It clears the blood from your view so that you can see where you're going when you fail to stop.

    I suspect either the airbag itself or movement of the driver's arms on impact might be a cause.  The wiper controls are next to the wheel.

    Water is forced out of the washer supply by the force of the impact, the wipers are then activated by the sensor?
