Even though I have some nice little battles with the Ai, from what I can tell is they lack some general awareness in some scenarios. Sometimes they abruptly close of space that is not theirs and if you don't get out of harms way you are done for the day. I like aggressive Ai as I do not like Ai that drive around single file and like a train, however I believe for a developer it is always that ongoing quest to find the right balance between aggression, intelligence and realism. I do not underestimate the complexity of this task.
What concerns me more is the collision model. It is alarming
