If I were designing these newer style aerodynamic handles, I think it would be done such that the handles default to the open graspable state. Retract them when the car is in motion for aerodynamics (is it really that much of a benefit?) such that when the circuit is de-energized in a crash, the handles return to the default open graspable state.

At least the Tesla handles I’m familiar with are entirely electrical: if you grasp it and pull but the door and whatever ECU operates it is not energized, then nothing happens. There is nothing resembling a mechanical door lock.
