Too drunk to exit. Too drunk to pull a lever.
The emergency door lever IS hidden, not marked, and in no way obvious to a person who rides in other normal cars.
You are making assumptions. Even if the driver was drunk or driving recklessly for another reason no one should die in such a horrible way.
Any way out whether it is in a building or a car must be easy find and to operate and available in an emergency.
Likely drunk ... yes. But the back door release isn't just a lever. You have to pull up the rubber piece in the bottom of the door pocket and then pull a release cable. Stupid design.
