Learning experience for a new driver

Still new to sim racing, so I'd really just like to know what I could have done better. From my POV, it looked like the lmp wanted to go through the inside, which is why I stopped steering in and he then drove into the back of me. He claims, I left the racing line and it was my fault. At the time, I thought he misjudged and drove into me. I was also frustrated, because it was the second incident with a prototype, the first of which cost me a chance at the podium. Any advice for the future woul
