I found this video by Adaly Debest on youtube were he uses an out of bounds glitch to reach the race track could this save time in the normal route?

the video by Adaly:

It saves time, and is already used, in Darker Side, All Missions, 100%, and World Peace. Dark Side currently doesn't use it, and it is still way slower than getting 10 moons without the race. A noticable skip, but nothing new
