Review the collision of the race leader with another car (I cut this lap in mpredit, collision happened in the 1st split)

Visually there was some gap between our cars but my car suddenly spoon when I just passed this lapped guy.

A little bit too big bounding box?

It looks to me like it was lag. Before you hit him, he was turning right, but then suddenly snapped left. In the replay, you were also fine for a few metres, but then you were spun. I'd put it down to lag to be honest, especially since both of you were lagging slightly at the time
