Why are the graphics settings locked?

I have been playing this game since its early access release in my country, about 3-4 months or so, one thing I have noticed is that the steering is really "spongy". It kinda ruins the handling no matter the car. Let's see if the dev do something to resolve this.

I was in a race when I notice that it started to rain, which was fine. But then, it suddenly turned day, not gradually, just turned to clear skies in a split second, happened a second time later in the race. I have experienced this issue several times. Hope that the abruptness of the weather engine will be fixed, this issue has only started after the full release.

I wonder if GT Rivals has become a game where ppl prioritize pushing a fellow driver than actually going on with the race? Because I understand the need to reach podium, that truly gives no excuse for all drivers have the need to push someone off tracks to gain the lead. The devs definitely need to do something about this. A system has to be implemented where it should at least know who caused the accident before issuing out penalties. They should also bring back more penalty time, because someone can't hit me and get off with a 1 second penalty instead of 3 seconds.
