Having waited months before leaving a negative review, I have concluded that this is the worst game ever made.
After much promise to fix issues and add more content, (neither of which have been addressed), I recommend you to save your money! There are 0 events for many entire class of vehicle including gr1, gr2, all formula classes & many more. This renders the game incomplete from the beginning as you cannot use 50% of the vehicles for events.
What does exist is not fit for purpose. You can't share replays because it always crashes whilst uploading. The AI don't follow any rules such as obeying blue flags and put you off the track. The weather system is hugely broken and the AI are sometimes immune to weather altogether. The "new cars" are seldom new and in any case, pointless buying because of the lack of events. The "random daily prize" isn't random and almost always results in a trivial amount of credits. Terrible awful game and such a shame for me as an avid gt fan.
