Driving down the A90 last night from Aberdeen to Edinburgh I was repeatedly held up by drivers "overtaking" in the outer lane at 55 - 65 mph. No concept of "get past then pull in" they'd sit there for mile after mile!
Now ok, 55 across the WPR is better than 25 on Anderson Drive, but if there's roundabouts, junctions, big lorries and twats then I forsee regular carnage and the road being closed for an accident just about every day!
It needs to be bulit like a motorway with slip roads and nea "blocks"
