I've seen games like Celeste and Crash Team Racing: Nitro-Fueled have this kind of solution, and honestly, it really works out well. Makes the games more fun to speedrun. And since PC and Console are separated only because of in-game times, wouldn't it make sense to have it be an in-game time/real time kind of thing? If Cars 3: Driven To Win works like that, it only makes sense.
