Pay by the mile

Here is a scary approach to funding infrastructure construction. Government officials in the UK are considering a proposal to charge drivers by the mile. Yeah, big brother is watching alright. Cars would be tracked using microchips and GPS technology and assessed a monthly fee based on the number of miles driven. The idea -- which is undergoing a test in Seattle -- supposedly has the dual effect of raising funds AND discouraging people from driving. Totally redefines the phrase "user fee," doesn't it?
