Given that they appear to be time travellers, i'm not surprised! Nah just joking - I guess it is a physics thing related to where the car is placed.
For me, it's on every car and every track over the past year. In other words, it's always done this (I have 135 hours in AMS2 so far).
Hmm i race and have not noticed this. But i feel we need to get very close before we can see them in the pits. I would love to make them appear soon so i can see them far away
