One variation of a method for dynamically querying a remote operator for assistance includes, at an autonomous vehicle: autonomously navigating along a roadway; at locations along the roadway, testing performance of a set of wireless networks; in response to degradation of the set of wireless networks, decreasing a sensitivity threshold for triggering remote operator events at the autonomous vehicle; in response to a condition at the autonomous vehicle exceeding the sensitivity threshold at a particular location along the roadway, triggering a remote operator event; during the remote operator event, transmitting sensor data to a remote computer system via a subset of wireless networks, in the set of wireless networks, based on performance of the set of wireless networks proximal the particular location; and executing a navigational command received from a remote operator via a wireless network in the set of wireless networks.
