Martin Cassini: The Case Against Traffic Lights

Campaigner Martin Cassini argues that our system for managing traffic is overdue for radical reform and should be based on trust in human nature rather than an obsession with controlling it. He says a drastic cut in the number of traffic lights would begin the transformation, saving lives, time and money.
