Why is every ranked lobby fucking disgusting?

I leave space if needed, i try to race clean, but nobody does that back. If I wont let space we both crash. If I follow cleanly and get DRS with ERS to overtake I get brake checked and the other car is fine and me spinning as hell... why is this game so broken why are the players so broken... AI with max difficult is much better OMG why is that

Rant off sorry guys...
