For Sydney taxi passengers it's worth knowing that the Ministry of Transport actively polices cabs and drivers. Whilst appearing anywhere they regularly attend locations involving large movements of passengers and cabs. Recently I noted their presence after the One Day Cricket International, monitoring the Fox Studios cab rank.
On Sunday evening I pulled into an Airport terminal rank to be greeted by two female passengers with golf clubs and luggage. It was obvious they needed a station wagon and fortunately one arrived behind me. One woman was sharp enough to immediately request a swap with a passenger destined for the station wagon. Done, too easy.
However the wagon driver stayed seated in his cab whilst the women started loading their own luggage. From nowhere a non-uniformed bloke was at the cabbie's window, flashed a badge and challenged him for not helping the women load up. Later I spotted this official climbing into a Ministry of Transport vehicle (click image).
So if you think cabbies can pretty much do as they like, they can't and never know when 'cab cops' will suddenly appear. Cabbies are answerable to the Police, the RTA, Ministry of Transport, Taxi Council, taxi networks, Airport marshals, taxi rank security, council parking inspectors...sheesh. And that's even before cabbies get home for more grilling!
