I want a new feature, which is available in several simulations. I do not know how to explain in English, I will try. The principle is to be prevented by a moving visual signal from the opponents behind and on the sides. The huge priority is to make this feature ultra discreet. It must also be activatable and deactivated in real time via a simple button, which would have been set beforehand. This device could take the form of a very discrete arrow, which would make a circular movement (an idea ) I specify that it has no interest if this feature is not extremely discrete. Thank you.
Radar app is what you're thinking about. There was a plugin that offered it, but, as you know, anything that writes to the screen is not yet supported and S397 has not published the protocol for modders to rewrite their code (unless it was published and I missed it?).
You can use Crew Chief https://forum.studio-397.com/index.php?threads/crew-chief-v4-5-with-rfactor-2-support.54421/
