1. A system comprising:
one or more computer processors; and
one or more non-transitory storage media storing instructions which, when executed by the one or more computer processors, cause the one or more computer processors to:
obtain map data including a starting location and a destination location for an autonomous vehicle;
determine, based on the map data, a plurality of travel times for a plurality of possible routes, respectively, for traveling from the starting location to the destination location;
determine a map age factor associated with at least a first possible route from the plurality of possible routes, wherein the map age factor represents an age of at least a portion of the map data associated with at least one segment of the first possible route;
select the first possible route as a driving route based on the plurality of travel times and the map age factor;
modify a set of driving parameters for the autonomous vehicle for the at least one segment of the driving route to facilitate collection of map data within the at least one segment; and
cause the autonomous vehicle to navigate based on the driving route and the modified set of driving parameters,
wherein the driving parameters comprise a threshold acceleration and a threshold amount of time for driving in a particular lane, and wherein the modifying of the set of driving parameters comprises increasing the threshold acceleration and increasing the threshold amount of time for driving in the particular lane.
