TL;DR

A secondary pathfinding option for more critical tasks.

What ?

Pathfinding in this game is very simple - this is great for biters and other things where their tasks are very simple and even if they fail it doesn't matter, "Oh, the enemy walked into the tree, how sad...". However, it's not very good for mods that's based on the utilization of pathfinding-based entities like "AAI - Programmable Vehicles". The pathfinding really ruins the experience for such a mod

Why ?

I've been playing a purely-AAI base recently, and the cars gets stuck all the time moving from A to B, additionally they often drive straight into trees and some other annoying things that really ruins the experience, especially the fact that they often just try to move from A to B in a direct line without even attempting pathfinding (Not sure if that's pathfinding related, or AAI-related, although I have a feeling the latter is at fault, but I don't know).

DARPA Grand Challenge, Factorio edition!

In this case, the movement of the vehicle is run by the mod, so there isn't really an actionable idea here

If the entity doesn't even attempt to pathfind then it cannot be pathfinding-related.

The game already uses multiple pathfinding priorities to choose which path requests to take on first, and this is accessible from the API by passing the low_priority flag to LuaSurface::request_path to give the request a low priority – or by not passing that flag, which gives the request a high priority.
