Given the importance of planned weaknesses in cars, like crumple zones, how do armored/state cars that don’t have these features remain safe in the event of a crash?

Question

I’m thinking specifically about how breakable safety glass is important so that you can escape through a broken window if your car falls into a body of water, or how crumple zones are designed so that it’s the car that gets smooshed, rather than your brain and organs. But official state cars, like Cadillac One/”The Beast,” have bodies that are way stronger/heavier than a normal car and bulletproof glass windows, so how do they protect the occupants if there’s some kind of freak accident?

(I realize that the best plan is to avoid such a situation in the first place, but given that Cadillac One is hermetically sealed to protect against gas attacks and has electrified handles to keep people from getting in, I can’t imagine that no one has ever considered “what happens if the car accidentally ends up in a lake?”)

The risks are different.

Official cars usually travel in convoy with escorts on closed roads; this reduces the risk for car/car collisions and even car to tree/posts collisions.

And in the case of a collision with another car, for example, the US beat, it is so heavy that it will crush the other car (use the other car as crumple zone).

Also, the drivers are probably expert drivers.
