The fact you need a seat belt and brakes to stop a car is of no consequence to what I've just said.
It shows that your claim that a force is needed to keep an object in motion is pure garbage.
The only possible reason you could ever say that is due to your belief that things can move forever in space.
No, the only possible reason I say that is because that is the logical conclusion from the available evidence.
Not everyone has the same willingness as you to just outright reject reality.
If I was going to just reject reality and believe in delusional BS, I would be a FEer.
Again, if your blatant lie was true, as soon as you stop having a force provided to keep up the motion, the object would stop.
It would be instant.
You take your foot of the gas and the car immediately comes to a stop with all occupants in the car coming to an immediate stop.
The fact you don't, shows that objects will continue to move when a force is not applied.
It shows that a force is needed to stop the object moving.
It will always slow down.
The reason it will slow down is due to air resistance (and other similar forces).
That is a force which resists relative motion.
If you take away that force, it doesn't slow down.
Again, this is shown by plenty of evidence.
We can look at how this force slows a light object down much faster than it slows down a heavy object.
If the object itself was just going to stop, there should be no difference.
But because the same force is applying to different masses, masses which resist change in motion, the lighter object, with less mass, is affected more.
We can also look at changing the resistance, where putting it in water causes it to slow more, and if you reduce the air pressure it slows less.
This can be projected to a point where there is no air resistance, at which point it doesn't slow.
Again, you fail basic mechanics. With that it isn't surprising you fail to have an answer for the simple questions which show your model is garbage:
Again, by what magic does your magical air magically maintain a magical pressure gradient?
By what magic does this magical air of yours magically make the pressure gradient proportional to weight of the fluid?
By what magic does this magical air magically stop the magical high pressure region from decompressing and pushing up the low pressure region above?
By what magic does the magical low pressure air above magically push down an object into a much greater force/resistance of the magical high pressure below?
By what magic does this magical air then magically decide to magically push up some objects instead of magically pushing them down?
By what magic does the air push things down and then resist that downwards motion so differently?
