AITA here?

Touge showdown, guy wasn't ramming me any other time. I drift around that corner and he suddenly takes a hard left into me as I'm lining back up out of my drift and gets sent right off the guardrail, then immediately leaves.

The first turn I definitely hit his bumper but he braked WAY sooner than I expected and the Silvia couldn't slow down in time.
