Issue description
It would appear that while pathfinding the four cardinal points, i.e. North, South, East and West, are considered before any other direction.
Scenario
Rectangular open space, corners numbered 1 to 4 starting top left.
If a vehicle needs to go from 1 to 3 i.e. diagonally they either go 1,2,3 or 1,4,3. They never go 1,3
What is missing are the four diagonal directions, Nort West, North East, South West and South East. If there werew eight directions considered instead of four vehicles would work much better.
Vehicles spend so much time using a zig zag course that many game hours are lost in potential transport time.
