Me not.
AC suppose to be simulator, not just any game so let`s have "league" mode with all kind of shapes but same physics to level the field, is not what I would like to have. If someone do the mod and ask money for it, he need to make it worth by giving his best shot to find data and make it closest to rl as can be.
Frankly, I`m much more enjoying road cars in AC because they are closer to old cars that I like so much. Without assists "that make you faster" by correcting your mistakes or doing things for you because you can`t be bothered.
But that`s just me
