The guys from Rockstar Games long and carefully sifted through the creation of users in Social Club to select those works that look holistically only in the form of a series of multiple tasks. Below you can find the best three of them (one mission available for XBOX 360 and XBOX One, one for PC and one for consoles PlayStation family). As the regular user tasks, you can add them yourself in Social Club to try in the future.
Z-Games Rallycross Tournament from the author Kelchan (Xbox 360 & Xbox One)
"A 4-track list of technical tracks in and around the Maze Bank Arena, chock full of fast and slow sections, sharp corners, kicker jumps, a big jump, corkscrews, cross-sections, narrow passages, and speedy straightaways."
