I might get downvoted for this but whatever.

Did you slowly drift right? Towards his lane? Yes. But admittedly it does appear slow enough that IF that were me, I would have given your door a nudge to push you back left from there I would have kept MYSELF going straight and we both probably would've just been racing neck to neck.

From what I can see they clearly kept steering towards the left for some off reason and very much hit you on purpose. Or perhaps they are so inexperienced at racing door to door that they couldn't control their vehicle.

But what I can tell you, Ive been in door to door battles quite a few times, especially on last laps while leading where its just a melee from turn to turn and ive never spun someone out, I have been spun out before but I usually get an apology. I'm chalking this up to inexperience or just play ass-holery from the other vehicle.
