Well there is one corner in the entire game that is so difficult to master you will probably want to smash the monitor while playing. It's in Nordschleife, the Karoussel part. This corner is so hard to master that the only car capable of doing it seems to be a stock Audi S4. Yep, faster cars or other slower cars won't work. But this one will.
I've wasted a lot of time trying to master this corner with all types of cars, with no success. I had to race so much in Nordschleife that I know that track by heart now (which is a good thing). I levelled up 6 times just trying to master this corner. Since this corner is in the middle of the track, it takes about 4/5 minutes to get there, and if you fail... well I think you guess what happens.
Here's a video of this mighty thing. I'm not the only one having a hard time with it, by all the comments I saw on YouTube and EA Forums, this will soon be crowned the worst corner ever in racing games history. No joke!
