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 ?

The engine is generating force to keep the car moving at a constant speed against air resistance, but the overall speed of the car is not creating any force.

In other words, the force the car is generating is determined by the mass and acceleration of the engine components, not the overall speed of the car.
