I have a idea: In LFS you can choose any of those pitboxes to pit and repairing/refuelling a car...
But what about if:
...if every racer has a "solid" pitbox, so you can´t anymore choosing it...
And if beginners need help or don´t remember what number of pitbox it was, I think it can be shown : /w pitnum = show your number of pitbox to pit
what opinion? I think this is more realistic for racing
HINT: If still can´t get about what number it was, pressing 4 shows your racingline but also your pitbox as a red. would be a bit easier

it may be possible to do something like this atm as well, but will require coding. I remember Filur being able to detect the pit exit line and who crossed it ( = penalty). It could be possible to allocate a pit box for each player with something like this, and pop a system message or an rcm_ply with the pit box number up when someone enters the pit area.
