Criminal psychologist Adrian Raine proposes a solution for getting stuck behind dawdling pedestrians on busy streets – divide the pavement up into slow, middle and fast lanes! Slow lanes are for the elderly, child strollers, umbrella holders, the inebriated – and those dreadful cell phoners who crawl along and then stop dead right in front of you. The middle lane is for your average pedestrian - but if they hog that lane for more than 10 seconds, they get ticketed by 'Pedestrian Wardens'. The fast lane is for people in a hurry, but there’s no fine for speeding because people need to get a move on in life. And finally, its three strikes and you're out! After three tickets you're banned for life from pavements and have to take a door-to-door taxi to get to wherever you want to go.
