Web\$\begingroup\$ To add to this: as you do your routing on a fixed grid, parallel lines will be at least 1 gridmark away. If they make a corner together a 45° angle gives the most space between those two tracks on the diagonal. Different angles may require that these tracks start farther apart to ensure minimum spacing, resulting in less dense routing than optimal.
