..or better still, Councils can inform the Apps that certain residential roads are now 'closed' so they no longer get used by as much through traffic, but they don't actually close them so there's no inconvenience to local residents. I think HGV SatNavs work like this, with, for example, the London Lorry Control zone programmed in so trucks avoid residential streets inside the zone even though there's nothing to physically stop them.
