Uncontrolled flight into terrain remains the number one cause of accidents.
Uncontrolled flight into terrain is not an accident cause, its an accident result. An accident in flight that does not end with "flight" into terrain, is probably not that serious an accident
But seriously... If anyone with an IR/eIR/IMCr thinks that an autopilot is required to fly IMC, they should immediately go to the nearest authority and deposit the rating!
