1 - Start race replays from the 3, 2, 1 countdown instead of from Go. This way if people want to use replays with in-race footage for Youtube it’s a lot easier to get the entire race.
2 - When a lap replay restarts keep the previous view settings including hiding the on-screen controls. For the same reasons above.
3 - Add the race time to the options. As above so replay and in-race footage can be synched together easier.
4 - Update controls so that everything can be done with a controller and not the on-screen controls. That way if you are making a YT video you don’t have to have the display showing.
