You know, I feel bad for you, because you literally described the actual state of GT Sport perfectly, and knowing how reddit work, they will downvote you for telling the truth.

At the end, I just simply given up on this game, I uninstalled it (digital version) and started playing other games.

I now come into reddit only to laugh at people desperately trying to play this game in a legit way (fast and clean) and watch some video showing how the game is getting worse day after day.

Yet, those players are like casino gamblers, they always thing that the next race will be better, and it end up being worse........ (repeat the same processes everyday, until you realize that you are losing your time and your zen with this game)
