I use the ESC when finished on the "track", to exit and move to another car or track type. Just quicker than using keyboard. I sure don't see ESC in the UI assignments. I'll research about external applications.
Thanks so much
If you are referring to the option I think you are, it places you back on the track in a ghost mode until you get moving again. If you have a big off and don't want to drive back to the track, you can hit the rest button and it will place you back on the track.
I've pressed reset before (it was bound to one of my T500rs as a default), and when I would press it, car would be on track, but it also looked as if it had changed FOV also???
