consider letting cars move more freely

[plexsoup]

There's only 5 intersections worth noting, and pathfollow2d is directional, so we'd only need 16 paths (edges) connecting 5 nodes (intersections)

Instead of having paths snake around the whole map, we could have short paths between the intersections, then move the car object from one path to the next, given the limited options at each intersection.

with the time available, this isn't likely
