Look if no one wants to have a ghost car during game play, then maybe there should be a ghost in the replay at least, just like there is on the world rally championships where it shows everyones car at once on a virtual replay. That way, ur not actually chasing a ghost car, but then ull be able to see the differences in line and braking points, and splits. This way it doesnt make the game more unrealistic, but probably adds to the realism in the analysis side of things. As most have said, ghost cars do help in getting quicker no doubt. It should be there to gauge precisely where ur going wrong, a lot of racing sports do use some kind of gauge to see where your going wrong eg swimming where they have the WR line going along with the swimmers. In LFS the game itself without any addons or wotever, i dont really see any gauges that compare another driver to another
