Because the only known Clash race in the Piston Cup is the 2022's RPM Clash. now, i'm not sure if we should add a clash to each Piston Cup season because it would cause serious problems to the statistics of each racer. And it would take forever to add up all the wins and stuff and there would be many issues. if we add clash races to each Piston cup season, then I'll respect it, but it would add a whole ton of maintenance PLUS the issues we are working on right now.
