Sounds real familiar! Late one night, we (my girlfriend, now wife of 42 years), her brother and his friend were riding in his VW Bug. It was a warm Fall night, and it started raining. We got off the highway exit ramp, and headed up a minor divided road. This road was in a valley with cliffs on either side. Suddenly, the rain beating down on the windshield froze solid, and there was an inch or more of ice on it. The road instantly took on an inch or so of black ice. The car was going through a very gentle curve, and slid sideways into the gravel at the side of the road. The wheels caught in the gravel, and before we knew what was happening, that Bug flipped 1 1/4 times like a giant beach ball, and we ended up on the passenger side. None of us were wearing seatbelts, being dumb teenagers, so my future brother-in-law (the driver) and I (in the back seat) ended up piled on top of the two on the passenger side. We all crawled out of the driver's door. The only injury was to my girlfriend, who'd slammed the side of her head into the rear passenger window. We stood there in a daze, wondering what we were going to do. As we stood there, cars came down the opposite side of the road at the normal 45-50 mph, and hit that black ice, and instantly turned into an automotive pinball alley. We four pushed the Bug back onto all fours, and to our surprise, it started right up. We drove it up the side of the road in the gravel at about 2-4 mph, wobbling as it went. We walked several miles to my girlfriend's house. Later, my future brother-in-law sold me the Bug for $50. A friend had a Baja bug that needed an engine, and we made an agreement that I would put my Bug's engine in it, and sell the Baja, then we'd split the proceeds. Will never forget rolling that Bug!
