Imagine you were able to throw a ball in a frictionless environment
such as outer space. Once you let go of the ball, it will travel forever
in a straight line, and at a constant speed. (At least until it bumps into
something.)

A car accelerates down the road. The reaction to the tires pushing
on the road is the road pushing on the tires.
