Efrat, they ignored the historical topography, road systems and environmental characteristics of the West Bank, and simply formed an apartheid network of "octopus arms which hold a grip on Palestinian population centres". A large number of embankments, concrete slabs and barriers impeded movement on primary and secondary roads. The result was to cantonize and fragment Palestinian townships, and cause endless obstacles to Palestinians going to work, schools, markets and relatives. Ramallah was cut off from all of its feeder villages in 2000. Though prohibited by law, confiscation of Palestinian identity cards at checkpoints is a daily occurrence. At best drivers must wait for several hours for them to be returned, when, as can happen, the IDs themselves are lost as soldiers change shifts, in which case Palestinians are directed to some regional office the next day, and more checkpoints to get there. Even before the Al Aqsa Intifada, UNFPA estimated that 20% of pregnant West Bank women were unable to access prenatal care because of the difficulties and delays caused by crossing checkpoints, and dozens were forced to deliver their children on the roadside. Constant uncertainty and the inability to plan are the results for Palestinians of the Israeli military rules governing their movements. The World Bank noted that additional costs arising from longer travelling caused by restrictions on movement through three major routes in the West Bank alone ran to (2013) USD 185 million a year, adding that other, earlier calculations (2007) suggest restrictions on the Palestinian labour market cost the West Bank approximately US$229 million per annum. It concluded that such imposed restrictions had a major negative impact on the local economy, hindering stability and growth. In 2007, official Israeli statistics indicated that there were 180,000 Palestinians on Israel's secret travel ban list. 561 roadblocks and checkpoints were in place (October), the number of Palestinians licensed to drive private cars was 46,166 and the annual cost of permits was $454. These checkpoints, together with the separation wall and the restricted networks restructure the West Bank into "land cells", freezing the flow of normal everyday Palestinian lives. Israel sets up flying checkpoints without notice. Some 2,941 flying checkpoints were rigged up along West Bank roads, averaging some 327 a month, in 2017. A further 476 unstaffed physical obstacles, such as dirt mounds, concrete blocks, gates and fenced sections had been placed on roads for Palestinian use. Of the gates
