I don’t think the point of the collar is to stop a cow going somewhere stupid, but rather to influence them to move to feeding areas and milking stations.
If a cow automatically moves to the right area then they don’t have to be herded. This reduces time. Some cows will likely need encouragement but it sounds like this reduces not only time, but stress on the livestock.

Fences are still likely needed.
