Could app spell the end of the traffic warden?
It is a scene every motorist has grown to hate. The traffic warden looming furtively in the shadows, licking his pencil waiting for the meter to click so that he can pounce and issue a ticket to the poor unsuspecting motorist whose only misdemeanour has been to underestimate the length of the queue in the supermarket, or the time it takes to process a prescription.
