Just to dot the i's and cross the T's. Its best to have answers that supercede even stadard cars that end up in water. Its seems the doors of the Aptera may be harder to open if submerged quickly. I recommend the car comes with AutoXcape on the doors, just as a sobering reminder that Aptera cares when GM does not. This device will not only cut the seat belt strap, but break the remaining window for an escape once the water fills the cabin. How exciting, if your that unfortunately hit on a bridge or uncareful.
