How about adding each city to full-game leaderboard or as a misc. category? Im personally cant run this game due to i sold my ps2 but i would think that some people could run this if we have shorter categorys. Who knows i might get ps2 and run this game at somepoint.

Well, it's obvious that clearing 1 city is faster than clearing the whole game, but I think there might be a problem with this, once you clear all the racers on San Diego and unlock Atlanta, San Diego's not over, if I remember correctly once you clear the racers in Detroit, near the end of the game the same racers spawn again on all 3 cities, so for SanDiego% for example, you'd still need to go through Atlanta and Detroit anyway.

However, a workaround for this is, we could add categories for unlocking Atlanta and Detroit. Though imo it's kinda pointless seeing the lack of interest in running the game, I'd be putting up times but I forgot to back up my save before formatting my PC, so now I have to go through everything again to unlock the tracks, and that took me a long time, which is why I kinda haven't done it.

Tokyo% could be doable seeing how Tokyo it's kind of its own thing, but again, no interest yet.
