If a car moves consistently at 80 kmh and it weighs at 600kg, is it not generating any force? since you know, a=0, am I stupid or is Newton ?

Because force is calculated through *CHANGE* in rate and direction of the velocity (speed with direction) and not through the velocity the object already has.
What you are thinking if is momentum where P(power)= M(mass) x V(velocity).
Edit: Also as you asked: “is the car not generating any force”, force cannot be generated out of thin air if there is no other transfer of energy in the system. Meaning that if there is no combustion, propulsion, friction, or any other way for energy to transfer, there is no force acting on the car which means the car is staying a constant velocity. One more thing, it is incorrect to say force is generated because force cannot be generated but it can act on a body from another source that transfers it’s energy like I said above.
You may already know this but just in case, force can also act in a body to slow it down, for instance when you step on the breaks in a car, the breaks are apply a force to the car by causing friction which transfers kinetic energy to thermal energy(heat). What I’m saying is you can have negative forces as well which means that it’s a force acting in the opposite direction based on your perspective.
