Shows best practice for stopping, yielding and proceeding through a stop sign as a group. While not technically to the letter of the law, yielding and proceeding as a group is safer and better for traffic flow than each rider stopping individually.
As an aside, the second and third stop sign in the video are placed in violation of the MUTCD. They are being used as traffic calming on a residential street. This misuse of stop signs reduces compliance and respect for the device by ALL vehicle drivers, and degrades the meaning of the device. Yield signs should be used instead.
