Am I the only one who has absolutely no trouble with the loop? O.o
I got through it my first time on a practice track I made a few days after playing the game. 3rd time I made it through without hitting any walls. I don't quite understand what's so difficult about it.
Well it probably doesn't help that most times you see a loop it has a booster right in front of it, the sudden boost in speed just as your preparing to enter the loop makes getting the entry angle correct and keeping it throughout the loop very difficult.
