Judging by his recent actions I would question whether Tavish Scott actually believes in the NTS, at least as far as taking steps to reduce (or more accurately reduce the growth in) road traffic.  Here's the 1st example where Scottish Executive has actually over ruled the public enquiry's conclusions and intends to construct a 9km highway costing £500m: M74 extension

Secondly Tavish Scott announced the (surprise) route of the proposed Aberdeen Western Peripheral Route (WPR) in May 2006.  The project calls for construction of some 46km of road at an estimated cost of £400m.  The proposed route will cut a path through the city's green belt and has encountered local opposition; in fact after making the announcement Tavish Scott left by a side door to avoid the public. Aberdeen WPR

When we also include proposals to extend the runway at Aberden airport and (later) construct a 2nd runway at Edinburgh airport it becomes even more apparent that the (tired) 'predict and provide' policy for road and aviation traffic is very much alive in Scotland.  I could write and ask 'where is all the oil to support all this extra traffic going to come from?'....but such questions will doubtless be ignored so what's the point?
