In AStar module, two agvs collided on top of each other!

The car in front, parking is unloading.The car behind also need to be unloaded.Even though I used the AStar module, the car behind would still collide with the car in front.Is this normal?What if I want the car behind to stop and wait?

One of the Taskexecuter is inactive (State idle). An option allows to ignore inactive members:

One object acquires one grid node. If you increase the Node Spacing, that the distances of objects match with their size dimension, you can prevent the collision.

A model does not imitate all physical attributes.

I've tried.I changed the size of AGV to 0.5*0.5 and I changed Node Spacing to 1*1。But the two cars still collide。You can look at the model I uploaded and you will know my problem.
