Well, what he has told about him getting back before hotpursuit started
is incorrect as here you can clearly see him driving to the nearest intersection and then turning back and driving towards criminal - Alnadhiry (who drove to the highway, though).
Plus, Montana was using that Prototype run mod (or whatever it is called, it increases the run speed like 5-10x times) in private world like 2 minutes before the hot pursuit.
So, I don't consider this to be a proper reason for unbanning him.
