Leaderboard information

The leaderboard says my lap is recorded by showing the semicircle, or the full circle if I copy a tune from another leaderboard driver . How do I watch the replay of my lap (or someone else’s for that matter)?

Unless you’re looking at a Rivals Leaderboard, you won’t be able to access the replay data as there is no option to do so.

So why take up room storing the replay if you cannot see it?
