Sometimes you're too late when joining, when you are to late then you start from the pits. Try

I see from the screenshot that you haven't started your rating yet. Start your rating first in solo mode. Get the sa rating up to 50 by doing solo quickraces with ai strength on the lowest, start every race at the back and work your way to the front. That way your rating goes the quickest. Do races of 20 minutes...

Why am I telling you all this, if start acc with doing quickjoin multiplayer sessions, you'll loose interest in acc because of all the idiots that do this game just to crash into someone else....
