I read in the other feedback thread that you are unable to stop the 'double path's' between buildings.
Might I suggest embracing it then? Create road tiles to make flush roads when placed 2 wide.Currently when you place roads in a 2x2 square they make a circle instead of a double wide road. Making a long line of them means you have figure 8's all along your road. I feel it would look far better if you simply added the tiles to fit with the fact that double roads are common, rather than the roads assuming they MUST be in a one tile wide line.
That's the plan actually. I just need to draw said tiles.
