An automatic cruise control uses stored information about speeds which the vehicle used at given positions in the past to control the speed of the vehicle at a current position. In this way, the vehicle may be caused to travel at speeds in accordance with past driving history of the user. The speeds may be adjusted or overridden by the user. In addition, where a prior driving history is not available, the system can consult a database of given speeds at given locations and those speeds may be used to control the vehicular speed.
