The passing technique for trolleybuses is actually for the lead bus to pull their rabbit ears down and reraise them once the other bus has passed (when I've seen it done, such as the case where one bus has mechanical trouble and is being replaced by another). When well executed, it's actually a pretty smooth maneuver that takes just a moment of cooperation, but I agree with your (main) point that it's not efficient enough to do in live traffic as a routine thing.
