Yah, you have players in teams of 2. One player is in a UF1 - 4 (female ) passengers, 50% restriction and 120kg of ballast. The other player is in a TBO (or pick any class, for added LOL use BF1s) The aim is to make your teams UF1 cross the finish line first. Theres two ways of doing it. 1 is to push your UF1 around really quickly so that you finish quickly, the other way is to basically crash the other team's cars so that your UF1 can trundle to the line unharmed.
I did that once (well more or less) professional, without the ramming other ppls team rule.
Was a fun event on ky1 and we1.
And weve driven the uf1s in reverse round circuits too, but thats another thing.
