The updates still just feel like PD adding random little bits to the game once they're done, as if they're still in pre-release development phase building the game up where it doesn't matter about how stuff is added, the public aren't playing it. You're just working towards finishing it.
They don't feel like cohesive updates designed AS updates. You look at other live service games, their updates feel planned, thought out, putting things together that make sense. Six months down the line you remember what was in the "Guns Galore" update in another game, GT updates are just a mish mash of random things that all blend into one.
It feels like "Alright these random cars are done, these codebase changes are done and tested, someone did a couple more events, push it all live and then carry on with some other random work ready for next month."
