EventLab tracks are the best addition to the Festival Playlist in Forza Horizon 5 IMO (together with Treasure Hunts… when they work ;D ). However, they lack a challenge factor.
In a rare case when racing with AI, opponents can barely reach the finish line, while driving alone is a tad boring and pointless.
So my suggestion is to add target times to beat in these events. It could work like in Gran Turismo: three medals/trophies to get and three rewards… or at least one target and one reward.
Yes, balancing the difficulty for players at all skill levels could be tricky, but I don’t expect too much. Even easy challenge would be better than no challenge at all
