OPENING THE DOORS WITH OR WITHOUT POWER -- To open the front doors from inside Model X, pull the handle towards you.
OPENING THE FALCON WING DOORS WITHOUT POWER -- Without 12-volt power, the falcon wing doors can only be opened from the inside of the vehicle. Remove the speaker grill from the door and pull the mechanical release cable down and towards the front seat, as shown below. After the latch has released, manually lift up the doors. Model X falcon wing doors are equipped with high tension springs that assist with normal door opening.
Front trunk Interior Emergency Release -- An interior release button inside the front trunk allows a person locked inside to get out.
This release button is active whenever Model X is stationary. Press the interior release button to open the front trunk, then push up on the hood.
Note: The button glows for several hours after a brief exposure to ambient light.
Opening with No Power -- If Model X has no electrical power, you can open the rear trunk from inside. Use the mechanical release cable located on the underside of the liftgate, next to the interior light.
1. Remove the cover by pulling its lower edge very firmly toward you.
2. Pull the cable to release the latch.
3. Push the liftgate open.

If the above does not seem like it would work out then first question how other cars/vans work and/or determine if this is too risky then purchase whatever is best for yourself / family. Flipping the lower center of gravity X or S with the heavy battery is highly unlikely compared to other non-ev vehicles.
