NOT a great surprise that plans to record every word uttered on taxi journeys through Oxford could face a legal challenge.

As Deputy Information Commissioner David Smith explains: “The recording day-in, day-out of every conversation in a taxi cab is likely to be going too far.”

He has as well suggested that recordings should be deleted immediately after uneventful journeys, rather than kept for a month. Which doubtless suggests we haven’t heard the last on this issue.
