It's correct, though; it's not attached to the drivetrain of the vehicle. Ruling that any GPS device capable of tracking distance constituted a "taximeter" and was therefore banned from private cars would be an unworkable disaster.
(Hmm, I wonder how Uber's metering copes with the Blackwall tunnel and the Woolwich ferry. My GPS directed me over the ferry once, resulting in a huge delay. Note that on the ferry a GPS would count as "moving" but a taximeter "stationary".)
