How do firefighters open it if you're injured or unconscious?

Break the window.
It may be a surprise for you but in modern cars doors get automatically locked when driving. So outer handle is absolutely useless unless it gets automatically unlocked after the accident, and it likely won't if crash was serious or car does not have post accident unlocking feature.

Most modern cars will detect when an accident is happening, and while for a human that's an incomprehensible short time, for the electronics, servos, and motors that's an eternity to still do things. Some modern cars will do things like activate the brakes, tilt seats away from the side, tension the seat-belts before there's even an impact, pull away the steering wheel column, etc. So I wouldn't be surprised if unlocking the doors and trunk is part of such a system.

I think Teslas also blow a pyrofuse to isolate the battery pack in an accident

From what I found:

--- Quote ---Model S unlocks all doors, the trunk, and extends all door handles.
--- End quote ---

--- Quote ---It's also widely implemented. FCA has an accident response system that unlocks the power door locks as long as power remains intact for the split second it takes to unlock them. Volkswagen and Mercedes systems also unlock all the doors in the event of an accident. Ford and Lincoln's automatic door unlocking system is on a six second delay. This allows the doors to be locked for longer if there's a secondary crash, but then there's the question of power afterwards. Honda's system doesn't unlock any doors automatically. GM says that given a crash of "sufficient severity," the doors will unlock; they are also meant to never lock during or after airbag deployment.

No need to overcomplicate it; just add a fifth wheel to pivot...

all steel has some spring back that has to be accounted for when bending and pressing
