@pawel567 Probably because it is still time and resource consuming to add these tracks with the AI training, and this being an annualized franchise.
Let's say it's around release time and your whole AI department is Dev A, a senior developer, and Dev B, a junior. They're full on working on the AI as a whole and for the DLC tracks upper management decided to include in the roadmap.
The game's released, management puts Dev A to work on the next project and assigns Dev B to work on fixing the AI related issues that are flagged by the players.
If they decided to release more DLC tracks, they'd need to hire Dev C, a good guy who supports Liverpool and likes barbecue. But upper management does not want it, they're adamant about sticking with the annualized model while keeping costs as low as possible even if that entails releasing.
Worse even, Director A had the brilliant idea of creating F1 Life, so now Dev A and Dev B cannot even dare to ask for a little bit more budget as that's compromised.
TL;DR: Codemasters have said a few times already that AI training is complex and can take up to 6-8 months for a brand new track, and the same devs who would be working on that still need to fix AI related bugs and are in a rush to wrap it up and move on to their next game.
Germany, Vietnam etc aren't completely new tracks and relatively recent. Probably would not take that long. Would still be very time and resource consuming, as the AI is not following the same parameters from previous games e.g. new handling.
