Not sure if it is an option, either by a hack or a mod, but an F1 game for the ps2 had an option for a parade lap, it was good to begin with, but soon got annoying after about 3 or 4 races and ive never used it again.
formation laps in single and multiplayer worked perfectly in GTR2 and rFactor so I have no clue why on earth SimBin chose to not include them in RACE. It's just bizarre. Same thing with the day/night cycle... All of those things are already in the engine, so why would they leave them out?
I would also like to see the Parade and Warmup laps as playable options. I've done a race or 2 in rfactor with the manual warmup lap and I really liked it, it seemed to make the start of the race a lot more intense and got me much more into than the traditional plop on the grid start. Maybe simbin will bring these back in Race On.
The parade lap and post-race in lap were one of the big things for me that separated GTR from other "racing games"; I always drove both. When I got GT Legends, and now GTR Evolution, I was dissapointed not to get either as the sensations of both were similar to what I feel when doing the same when Karting. If GTR2 has them, I might have to relinquish my "Cats and Radders" for the sake of a more genuine racing experience.
