The political wing of the Provos won a seat on the city council of Amsterdam, and developed the "White Plans". The most famous of those is the "White Bicycle Plan", which aimed to improve Amsterdam's transport problem. Generally the plans sought to address social problems and make Amsterdam more liveable.
List of the White Plans:
White Bicycle Plan: initiated by Luud Schimmelpenninck, the plan proposed the closing of central Amsterdam to all motorised traffic, including motorbikes, with the intention of improving public transport frequency by more than 40% and to save two million guilders per year. Taxis were accepted as semi-public transport, but would have to be electrically powered and have a maximum speed of 25 m.p.h. The Provos proposed one of the first bicycle sharing systems: the municipality would buy 20,000 white bikes per year, which were to be public property and free for everybody to use. After the plans were rejected by the city authorities, the Provos decided to go ahead anyway. They painted 50 bikes white and left them on streets for public use. The police impounded the bikes, as they violated municipal law forbidding citizens to leave bikes without locking them. After the bikes had been returned to the Provos, they equipped them all with combination locks and painted the combinations on the bicycles.
White Chimney Plan: proposed that air polluters be taxed and the chimneys of serious polluters be painted white.
White Women Plan: proposed a network of clinics offering advice and contraceptives, mainly for the benefit of women and girls, and with the intention to reduce unwanted pregnancies. The plan was for girls of sixteen to be invited to visit the clinic, and advocated for schools to teach sex education. The White Women Plan also argued that it is irresponsible to enter marriage as a virgin.
White Chicken Plan: a proposal for the reorganization of the Amsterdam police (called "kip" in Dutch slang, meaning "chicken"). Under the plan, the police would be disarmed and placed under the jurisdiction of the municipal council rather than the burgemeester (mayor). Municipalities would then be able to democratically elect their own chief of police. The Provos intended for this revised structure to transform the police from guard to social worker.
White Housing Plan: sought to address Amsterdam's acute housing problem by banning speculation in house building, and by promoting the squatting of empty buildings.
White Kids Plan: proposed shared parenting in groups of five couples. Parents would take turns to care for the group's children on a different day of the week.
White Victim Plan: proposed that anyone having caused death while driving would have to build a warning memorial on the site of the traffic collision by carving the victim's outline one inch deep into the pavement and filling it with white mortar.
White Car Plan: a car-sharing project proposed by Schimmelpennink featuring electric cars which could be used by the people. It was later realised in a limited fashion as the Witkar system from 1974 until 1986.
