Yeah I've noticed that too and it kinda destroy the race, as earlier to day a FRR2 race starting grid 22 cars ending 5 cars it look so.... not good.
Maybe it is a change for future features like the ranking-system to divide those who really DNF due to technical problems and those who rage quite...
Yea but still if you enter a race and end up as DNF then that is your score. So I think no matter what planes are for future DNF should still be in the list of those who started the race..
