As far as what daox said, 1 mph at 5 is not the same as 1 at 40 mph. The kenetic energy scales with the square of the speed. You can illustrate this by coasting up a hill and observing the vertical displacement will be significantly more as you slow from 40 to 20 as it will be from 20 to 0. However if driving a manual anyways keeping the speed above your first gear idle rpm will reduce clutch wear which is good
