Firstly the positives: This is probably going to be one of the most significant features in simulating F1 races or any racing series which uses DRS. I think that it changes the game hugely with the DRS and while I haven't tested it too much I had one of the best experiences driving F1. But also the tyre changes is I think even more significant feature. AC notoriously has lack of pitstops so the only thing you could do was force the AI to pit manipulating the fuel size and etc. I haven't run any longer races but I hope that it brings something new to the game. Also with the threshold it would be great if the threshold could be set with little variation +-3% or something like that think it would add some kind of strategy to the game. And maybe later even forcing AI to use different compound after pitstop.
Now the let's say negatives: Installation is a bit tricky, and I can see inexperienced people struggling a lot with making it work. You could maybe make a video guide how to install it because most of the people do not know how to enable developer options in CM, or pack, unpack data etc. Also it makes cars unusable online with packed data. In game app needs to be enabled and you know that only by debug screen or that it's highlighted in apps bar, think some icon with on or off could be nice. And the only thing I struggled with is that every option is enabled and wet tyre option basically brakes AI on start if it's enabled they just don't go, and I didn't know what was causing it(I was using Kunos SF70H).
But all-in-all I think this mod has enourmous potential and it would benefit from integration with CM and F1 mods from start and I love that it exist, that someone made this possible, and hate that I only found it know.
P.S. maybe don't include F1 HUD with this mod later because it's graphical mod and this mod is more CSP-physics-mod with wider use, but I would download it nevertheless :)
