Like "clubs" from Rocket League. You can have "clubs" or "clans", that may be private, invite-only, public, etc. Maybe clans could have their own prefix/clan-tags, like those from Call of Duty. Maybe you could look at leaderboards for clans (that is, sort a clan by players' ranks, or look at the leaderboards on a map for only runs submitted by clan members).
A map is a part of a clan’s territory based on the clan members with the best times on the map.
This could be done with something like 1 point for your clan for a top 10 (2 for world record), and based upon either whoever has a majority the map becomes this clans turf. In practice this probably will work well being done by rank xp.
When playing on your clan’s map there could be some kind of bonus like 5% more cosmetic xp.
Fastest Clan/Sum of Bests
Take the fastest pr from any clan member for every map and add up the total amount of time to see which clan is the fastest.
E.g. clan A has 5th place on 3 maps with exactly a 1:00 pr on each one. Their total time is then 3:00. Clan B has 2nd place on 3 maps with a 0:45 pr on each one. Their total time is then 2:15. So clan B is the faster clan with a faster sum of best.
General Leaderboard Stats
Track stats just like the player with potential clan specific additions like total number of map wrs, course wrs/wrcp, bonus wrs, rank xp, etc.
Clan Exclusive Cosmetics
Clan Ranks
Fastest in the clan, most wrs, most cosmetic xp, founder/leader, etc.
Restrictions on Creating Clans
Place some sort of restriction on making clans to avoid having a whole bunch of irrelevant, noncompetitive clans with only a couple people.
A certain amount of rank xp could be a good requirement to create a clan, or alternatively a certain number of map world records.
Clan Tags
Visually distinct from steam alias
Raids (this could use some refining/changing)
Clan members could raid a map by grouping up and trying to obtain a certain amount of rank xp with a bonus to take control of the map territory in a set amount of time
With some work raids (or another co-op mechanic) could be a good motivator for those people who are not quite the best of the best but above basic completion to play more. I only mention this because I recall some discussion somewhere in the discord about struggling to provide more incentives for these kinds of people to play and improve.
