He entered the turn too wide, and there are people about to mess up just in front of him, and he barely touched the brakes. The guy behind him probably didn't have the time to react so yeah no real point to complain.
On the other side, if you don't touch the brakes in these situations, you're part of the problem.
But I get it, you wanted to complain about a guy that complains. Makes total sense.
The SF are stupid to drive outside of a super clean and experienced lobby like pretty much all powerful and supelight cars that have loads of downforce. I did not race Suzuka because I tried the campaign Suzuka race on the first day I bought a SF, and I knew that any sport race on these cars would be a crapshow. It could maybe work on wide tracks, or in the finals of FIA races, but not on the regular GT sport mode with regular dirty and sloppy drivers.
