<span>At lower speeds modulating speeds is a must for safety. I would be hard pressed to find a place in town you could drive 25 mph for an extended time. Also, plan on a lot of shifting at lower speeds. That completely negates using the cruise on a manual and really puts the auto in the hunting mode. I would think it safer that you move the selector into a lower gear to get some engine braking at say, 25 mph which would make it easier to sustain the speed rather then use the cruise.
