I'm a bit confused with the question below. Particularly, I'm confused what the difference between driving force and net force is.

For driving force, I easily find $$F_D = ma = 1000 \times 0.3 = 300$$ Problem is, I'm inclined to find $F_{net}$ as, $$F_{net} = F_{res} - F_D = 200N$$

The correct answer, however, is $300N$.

"Net force" is the sum of all forces acting on an object.

"Driving force" is just one specific force acting on the car in this problem.
