...but he didn't get his head sheared off, because other structures around the cockpit deflected the other car, which is also a viable solution that so far has been very effective. We've seen people routinely walk away from some horrifying-looking rollovers because of this.

Besides which, if a quick escape is needed, pyrotechnic fasteners (explosive bolts) have been in use in aircraft cockpits since at least before the time of the English Electric Canberra bomber which flew in 1949.
How would that work if the car is upside down?
