They talked about the AI pathing being a bug, and as 1.2 is the big bug fix it makes sense that they will address it. Esp given its prominence in many critics eyes. It's more of a distraction that eats away at immersion than anything else versus game-breaking, but I would envisage getting it rectified would go some way to demonstrating that CDP is fixing things. Esp after 1.1 didn't fix a lot of things outwardly versus address stability and performance.
Iwinski stated they fall under the category of a bug and would be fixed, doesn't mean 1.2. It could be, I hope so, but I don't really see that happening any time soon. There's evidence that chases and vehicle combat existed in some form, I know because the Valentinos tried running me down while shooting at me on two occasions, but I could never get it to trigger intentionally. That being said, this probably results from another streaming issue as the game shits it's pants when you drive faster than residential zone speed limits. It's probably why the story chase scenes run at ten miles an hour with granny speed turns around corners. As for performance; My performance degraded actually, and many other PC players have reported the same, so I'm not sure what came out of 1.1 other than some console improvements.
