world improvement proposal:

Invent elevators that can be safely used in case of fire, so that disabled people who can't use stairs can still safely get out of a building.

This would probably involve a backup power supply for the elevator and air filters on the elevator cabin.

Of course those elevators would be supposed to be ONLY used by disabled people in an evacuation (in regular service everyone can use them). For people who can use stairs, it's still better for them to use the stairs in an evacuation.

@LunaDragofelis most high rises and even mid rises now are poured concrete. They’re basically giant concrete boxes with stuff inside.

If my next door neighbour’s apartment is on fire, the safest place to be is in my apartment.

It’s physically impossible for the fire to reach my apartment without active human intervention.

Keep the door closed so smoke can’t get in, and let the firefighters do their job unimpeded.

The elevators should even be safe to use at that point, but the firefighters don’t want to have to compete with the auto logic doing unexpected things.
