I don't expect this update to be popular with players that use analog inputs at all. I think casual players as a whole will be turned off, because it seems like a big step to a more hardcore sim direction.
If it's true that 80% braking becomes the new sweet spot for ideal driving, then that's fantastic for skilled wheel and controller users, but literally (and I mean literally!) impossible for people using the face buttons to brake efficiently, and a harder thing to manage for more casual players using other methods than just slamming the brake trigger all the way down.
It will be interesting for sure. The physics seem very obviously geared to competitive sport mode play and that's just, for better or for worse, not where the bulk of the players are.
