a caution range and a warning range; and
communicating an alert to the operator of the vehicle via an output device that includes a haptic device, the alert responsive
to the current speed range and to the operator alert preferences, wherein:
the alert includes one or more caution attributes when the current speed range of the vehicle is within the caution range;
the alert includes one or more warning attributes when the current speed range of the vehicle is within the warning range;
and
the alert includes one or more at speed attributes when the current speed range of the vehicle is not within the caution range
or the warning range; and
wherein the communicating includes generating a haptic alert signal to activate at least one of a vibration and a poke of
