In the animation https://www.geogebra.org/classic/sr8fxezb there is the
force F of the hand that pushes the point A of the car.

The force F that pushes the car is certainly a "net" force because
there is no one to push the car from the other side.

But is the force F that pushes the point A of the car also a "net"
force?

A net force to the car is not a net force to a part of the car.
A part of a car has inteactions with other parts of the car. In addition,
gravity affects the part and the ground under the car touches or does
not touch the part.
