I'm not sure how important improving the AI in LFS is exactly, but having the AI, in LFS, is very important. If they ever removed the AI, I wouldn't renew my license for the newest version. I'm sure I'm not alone in that I play offline a lot, on pro settings it can still be a challenge, and because the AI are kind of stupid, and make the mistakes, it makes the race more challenging. To survive a race with 19-20AI is good training, and if on something like SO, it can be a great way for ppl to train and learn how to race before going online. There's more to racing than scoring hot lap times, ya gotta be able to avoid accidents, pit strategies, so, yeah, offline AI is what makes this Sim the best, along with it's multiplayer racing.
