Larson was on Wallace’s inside and his car drifted up the track. Wallace’s car hit the wall and then went left and hit the right rear of Larson’s car. That crashed both of them and also collected playoff driver Christopher Bell

Longer video here. See: Kyle Larson, Bubba Wallace make contact, cause wreck at Las Vegas

This video clearly shows that Larson's car never touched Blubba's. Blubba got skeered, drove into the wall, then intentionally wrecked Larson.

That’s what I saw...NO CONTACT until Bubba purposefully rammed the back quarter panel of Kyle.
