You technically can survive a 140kph crash in the same way that technically you can survive jumping out an airplane at 10 kilometers, or how you can survive rabies
Technically possible as there are few recorded incidents, but let's say that you easier win the lottery than surviving any of that shit.
Was it myth busters who smashed a car against a wall at 120 or 140 kph? Don't know anymore but I do recall the car literally being folded up
At those speeds, crumplezones extend way into the back of your head, so again, you can quite safely bet you'll die.
As intended
