the bottle will land in her lap
Near Earth's surface, the acceleration is about 9.8 meters/second2, assuming air resistance can be neglected.
If air resistance can be neglected, there is no effect. If there is air resistance, the general tendency is for more massive objects to fall faster. In places like the moon, where there is no air, a feather and a rock fall together.
a constant horizontal speed
then the vehicle will go faster.
With less gas inside the bottle, it will weigh less. But not by very much, for the mass of the volume of air is slight. If he bottle is evacuated, then its shape will change slightly - but once again, a small amount. If the bottle is fragile, it may collapse. This would be expected for a plastic bottle, such as a soft drink bottle.
The bottle will land on the interstate behind the car.
The bottle will collapse when the bottle has heated air
Near Earth's surface, the acceleration is about 9.8 meters/second2, assuming air resistance can be neglected.
It will implode.

The air in water bottle expands
Without air resistance? All three will hit the ground at the same time.
The air will rise into the upper bottle in bubbles while the water splatters and drips down into the lower bottle. No vortex is formed.
Because the air inside the bottle push out the wooden cork.
If you have eliminated all resistance then the initial force will be enough.
If there are no air resistance the hailstones would hit the earth at velocities near 350 m/s and melt before they hit the ground.
