How should a group of riders perform a passing maneuver on a two-lane road?

1. One at a time, with each rider completing the pass and returning to their lane position before the next rider begins.
2. All together as a single block to minimize the time spent in the oncoming lane.
3. The leader passes first, and all other riders must follow immediately without checking.
4. By riding side-by-side in the oncoming lane until the maneuver is complete.
