Showcase events haven’t evolved much since the first Horizon. They really are just a flashy time attack and there are no real stakes because the pattern is always the the same. As long as you dont bone it up too badly you always just barely beat whatever crazy thing you race against. Why not get rid of the position marker and make them more like the Horizon story missions? Just give a three star rating for hitting certain beats on time, like a check for jumping over the train or one for beating it to a checkpoint. A few requirements like jumping a certain distance, getting a certain speed zone/trap speed, etc that dictate the rewards you can win for finishing would give showcase events some replayability too.
