You can't drive between Edinburgh and Dundee on a motorway, no you have to drive all the way round Dundee and stop at traffic lights and navigate several roundabouts.
WTAF are you talking about?
How can anyone not be aware that the A90 goes through Dundee?
To get to Aberdeen from Edinburgh, you must drive on the M90 which shortly after Perth becomes a dual carriageway. Then it goes right through Dundee, with multiple roundabouts and traffic lights.
This is a fact. Even Nicola Sturgeon couldn't deny it.
While I'm at it, there isn't a motorway between Edinburgh and Inverness either. And the Edinburgh City bypass is a disaster. There is barely a time of day or night when its 3 roundabouts, Sheriffhall, Craighall and Hermiston Gait, aren't causing massive tailbacks.
Scotland doesn't have motorways between most of its cities, and there is no prospect of that improving soon. The reality is tailbacks lasting miles and journeys taking twice as long due to the inadequate infrastructure.
You are aware that most countries now have motorways between cities? It isn't particularly environmentally friendly to have quite so many lengthy traffic jams as a semi-permanent feature, no matter how much of the landscape you spoil with windfarms.
