1. A method comprising:
selecting, by a vehicle, a route to a destination by at least:
responsive to receiving a request to navigate to the destination, determining at least two possible routes to the destination from a current location of the vehicle;
determining respective availabilities of radar-localization objects for the at least two possible routes, the radar-localization objects having corresponding locations on a map and being usable by the vehicle to localize itself relative to the map via radar reflections from the radar-localization objects; and
selecting the route from the at least two possible routes based on the respective availabilities of the radar-localization objects for the at least two possible routes;
determining respective quantities or lengths of estimated driver takeover due to insufficient quantities of radar-localization objects for the at least two possible routes, wherein the selecting the route is based further on the respective quantities or lengths of the estimated driver takeover for the at least two possible routes; and
maneuvering, by the vehicle, to the destination via the route.
