Hey Forza Community! 
I BEG Turn10 to overthink the Multiplayer. It just sucks hard… I played for some hourse now, and im so angry with this game. Crashing into each other and cutting Corners by miles is normal… No fun at all, if you want to drive like it is actuall a simulator. I tried hard to drive like a normal racedriver, not like a maniac, but if you do, you loose every time even you have the fastet laptimes. Please fix that or at least, invent a new system for Forza 6. Thats not acceptable at all!
This is one of those times where the cliché “don’t hate the player, hate the game” needs to be flipped on its head. The issue you speak of isn’t unique to Forza … it’s prevalent in just about all racing games. The problem, however, is when you race in the public, these sorts of antics are bound to happen. When you see drivers abiding by your standards, befriend them and start your own private lobby sessions. If you keep returning to the public lobbies expecting a different result, you’re going to disappointed.
I don’t agree with “it’s in all racing games”. Turn10 make it very very easy to cut a lot of tracks. For some reason, Turn10 thinks its ok to do it on Yas Marina and even have a clean lap. On the other hand they messed up on some parts of the track with sticky grass or whatever. In my opinion it is not only the fault of those unfair players, they using what Turn10 allows them to do.
