I have a friend of mine who has done crash simulations on computers for years (primarily used in litigation cases). It's his opinion that any crash above 90 mph is not sustainable in a commercially available car, period. The forces are so great that even if the safety cage survives the impact, the forces that the human body will experience is a killer. To be clear, that would be head-on collions and running into a stationary object like the one shown. Other types of events such as rollovers have a greater life expectancy albeit with severe human damage. If you think about how a race car is built and the safety features that have evolved like neck and head harnesses, you can understand the differences in survival rates for racing vs on the street accidents. Plus, how many race crashes end up in a head-on with an immoveable object. Usually the forces are at angles, not perpendicular.
