Hi! I cannot answer this question:(adsbygoogle = window.adsbygoogle || []).push({});

The force that accelerates a car along a flat road is the frictional force exerted by the road on the car's tires. Explain why the acceleration can be greater when the wheels do not spin.

I know that friction is the force that is moving it forward and the answer is about the coefficients of friction, but I can't seem to understand that if the wheels do not spin, the acceleration will be greater because...well, won't the car remain stationary?
