Speed limits do not correlate at all to the current performance standards of the modern automobile. They are a safety standard calculated based on an efficient volume of throughput of the area during normal traffic flow in addition to environmental factors such as keeping noise low, reducing tire wear, and controlling emissions. Even with an apex of 90deg., an average performance car (I'll say a 4 cylinder Ford Focus ST off the top of my head) could handle a turn at 40-45 mph when taking the most efficient line. In fact, at 40-45mph one would be on the edge of even being able to pull the handbrake and initiate a drift around the corner (in the event one was really trying to be an idiot showoff) as speed would be too low to follow through and exit. He also worked right down the road, so one cannot argue he was unfamiliar with the area and driving it.
IMO, they were cruising around the corner as no one else was on the roadway at that time, and either the power steering line burst or a tire went. Either would be completely uncontrollable at any speed and either would have gone due to premature failure or defect as the car had less than 3k miles on it and can easily hold that speed and G's. This would also explain the lack of skid marks until closer to the cars final resting place (when they tried to avoid light/tree).
With that said, I'll fully expect all of you on your way to/from your homes today to ensure you're doing that 15mph on the on/off ramps or the 35mph on that gentle curve placed on the 55-60mph roadway........
