PS5 Tsw4 - Avl Rotem Cab Car: Impossible To Get Max Score

In TSW4 the max score a player gets per distance unit driven is 65 points. While driving the Rotem Cab Car correctly set up and with alterter (TMS) activated I only get 35 points iso 65. Being docked 30 points per distance unit makes it difficult/impossible to achieve platinum. Can you please look into this?

 

Apparently not. It's been a month since release, and not even an acknowledgment, let alone a fix.
