In any basic driving game not just racing sims there should be some degree of wheel spin or sense of traction or lack of when it comes driving the wheels.
I will admit that with heavier vehicles this may not come up due to weight but you should absolutely experience this when going full throttle from a complete stop in a ATV or truck, car etc.....
The best way I can describe this is as torque or wheel spin or just the initial search for traction when accelerating from a stand still.
