Direct answer
A team stops covering the same streets twice when every street has one owner before anyone drives. Split the territory into units a driver can finish in one session, with each boundary street assigned to one unit, and put one named driver on each unit in a record the whole team can open. The handoff matters as much as the assignment, because a unit that ends without a recorded stopping point gets driven again or left unfinished. So each driver records the drive under their own login and notes where they stopped, and a manager checks the recordings against the units the next morning. PropertyRadar's mobile app records GPS Tracks and sorts them by team member on its Solo, Team and Business plans, which covers the recording. Who owns which streets is a rule the team keeps for itself.
