How do I deal with getting consistently "shadow-realmed" on first turn?

As someone new to mainline Forza franchise, I've been really enjoying the game so far... if not for the fact that a lot of my races start with being bumped and then shuffled to the side, after which I end up stuck in the bottom positions for the rest of the race. Last game session, it literally happened for three races in a row, at which point I just felt too discouraged and dropped the game for a couple days.

I've tried to search for other threads on the topic, but haven't found any. Is there any general set of tips to handle the first turn in a safer manner?
