The door is either bent and can't physically separate from the opening or it's jammed against something like a tree/rock/road/another vehicle. Either way explosive bolts wont help you.
Breaking the window creates an instant smaller opening that's still big enough to get out of.
All the doors would need to be bent and can't physically separate or jammed against something to prevent EMS from pulling someone out. It's possible, but unlikely.
Not really that unlikely I'd say. From major pile ups where you'd want to get our PDQ, accidents where the doors are pinned, to more mundane mistakes:

All it takes is some fire.
The second accident should be something EMS can pull someone out of from other doors. People would be stuck in the first and third, but those images don't show vehicles being incinerated.
It's possible, but not likely to have both a multi-car or large vehicle pileup that blocks all the doors and a fire.
It's likely that your spine will have sustained some damage in an accident that jammed your doors. That means you want level extraction, which requires removing both driver's side doors and the B pillar ("total sidewall removal"). Pulling a healthy person (or an injured person if they need to be removed from the car right now) out of a car is easy, doing it without further spine damage is a lot harder. Practising it is great fun, though :)
I'd rather have as many options as possible in an emergency, however unlikely, especially since this has already been tried and tested by other luxury auto makers before.
