I really hope it doesn't come to the UK/EU.
We have enough problems with people driving ridiculously oversized vehicles and killing pedestrians and cyclists in avoidable accidents. Not to mention small roads, cramped car parks... seeing someone maneuver this around a normal multistory car park would be a sight.
The SUV was a cursed invention, I really wish it had never been a thing. Massive trucks like these as personal vehicles is just taking that to the next, most ridiculous level.

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 it was Jaguar that showed a hood that lifted when it detected a collision, to comply with the pedestrian safety regulations requiring a minimum of 3 inches of space between the hood and hard points like engine and suspension
Locked doors might be a way to make sure the doors don't open during an accident compromising the passenger compartment, if so you wouldn't want them unlocking until after the accident

hasn't "Pedestrian Detection and Collision Mitigation Systems" with automatic braking not become mandatory yet?, I know it's been proposed so it won't be long

Drive by wire, for instance, allowing to tailor the steering ratio depending to speed.

This has been tried before, and does not work. The reason should be obvious to anyone that's ever driven a vehicle. The closest to variable steering that actually works is the various 4WS systems the Japanese manufacturers used in the 1980s-1990s. Curiously they don't bother any more.

Strange statement and wrong.
My 2005 BMW 330i (E90) had active steering and it worked perfectly, I enjoyed it. The 5-series had it even earlier. It's a standard option not only offered by BMW (I think, didn't check other brands).

Well, you Brits brought the SUV over here with the Range Rover, the ultimate accessory for suburban housewives.
In the US, the parking slots/lots are big enough.
