Extraction Cranes: When a large accident happens or a car is stuck in a sand trap due to an accident extraction cranes are depployed. Despite heavy criticism they remnain a vital imachinet used in all motorsports world wide. With the safety car in the game... i dont see why this feature has not already been added in the game. Im really sick of watching cars vanish into thin air while behind the safety car, it would be nice to see those many unoperational cranes on track already come out and clear out the cars while we drive behind the safety car. It is also a smart way to bring back red flag incidents... while everyone else not involved in the incident follows the safety car back into the pits... a cut scene plays of the incident removel till race starts once again, a smart idea is to add skip scene like we already have during practices and qualys for those who want to skip it. And the most obvious it adds to realism and some much life to the tracks.
Debris removal after an accident: A good way to bring some life to the track is to have marshals remove dangerous debri left behind after a small or big incident where small or large ammounts of debris is left on track. Would be nice to add this feature in conjunction with the cranes while under safety car, red or yellow flags. A fun and smart way to add this feature is to also have the option to report to the engineer that there is debri on track when a marshall has missed a spot. it is then reported to the race director we already have in the game who then makes the automatic decision to remove it by: bringing out yellow flags or the safety car so the marshalls are safe... it is a good way to have the director make the decision based on the ammount of debri, dangerous factor(might cause driver injury) ,size or sharpness (puncture risk). This idea comes for those who might try to abuse the feature to bring out the safety car to gain an advantage when there is no danger or nothing on track at all or just to troll.
Extra stuff: Barrier damage could be a great addition to assist in red flag sessions and would put those marshalls to good use in order to fix or replace the barriers.
