1. A computer-implemented method for managing autonomous vehicles, the method comprising:
maintaining a navigation map of a geographic region, the map data (i) being maintained for operating a fleet of autonomous vehicles within the geographic region and (ii) including a map layer that indicates a set of routing rules for determining routes for the fleet of autonomous vehicles within the geographic region;
maintaining a teleoperations coverage map for the geographic region;
receiving, from a first vehicle, a first set of network performance data that (i) is generated by the first vehicle while the first vehicle operates within the geographic region and (ii) includes one or more network performance metrics for a first area within the geographic region;
updating the teleoperations coverage map based on the first set of network performance data, wherein the updated teleoperations coverage map indicates the first area as being associated with low performance for teleoperations;
updating the map layer based on the updated teleoperations coverage map, wherein updating the map layer based on the updated teleoperations coverage map includes updating or generating a routing rule associated with the first area; and
determining, based on the navigation map, a route for an autonomous vehicle, the route being determined in accordance with the routing rule associated with the first area.
