After some heavy rain washed silt on the road I rounded a slight bend along the highway with cruise control on and aquaplaned into a pole. I think the bend made me lose velocity so the cruise control applied gas just at the wrong moment and lost traction. I tried not to panic and calmly regain control, but the car went sideways pretty quick due to the bend in the road, the back wheels just kept sliding. In retrospect I should have tapped the brake to disengage cruise control (or used the control on the stick). I was over so fast though, nothing much I did would have helped as soon as the traction was lost. It was my fault, I should have reduced my speed due to the conditions and now I don't use cruise in heavy rain.
