I don't think we're talking about the same thing, personally. The CLR wouldn't have flipped if its front diffuser was longer; i.e. the gradient of the road exposed the venturi and stopped it from generating downforce. At which point the car (on the very crest of that small hill) was suddenly generating much more downforce at the rear than the front, which pitched the car nose-upwards just enough to cause lots of low pressure on the nose of the car (with a higher angle of attack caused by being on the upslope of a hill), which caused yet more upward pitching until the free stream could get under the car and cause lots of high pressure on the flat underside, and cause it to flip.
The "jump" I'm talking about doesn't exist any more, either because of reliable downforce and chicanes, or because the hill at the exit of the second chicane is smoother now.
Except the violent change in the aerodynamics was caused by the track surface changing height, causing the ride-height to increase...
I never said it was. Remember we were talking about the jump at Cape Ring being "unrealistic". The only thing unrealistic about it is that there is currently no way to make a driver pay for over-doing it.
