No idea. It looked really weird on his onboard. Half like he knew Lawson was coming, because he positioned himself on a really weird part of the track, and half like he didn't know Lawson was coming because he suddenly jolted his steering when Lawson got close. I guess technically he was off the racing line? And from Lawson point of view it's hard to estimate if he was actually impeded or not because he had to break anyway. Probably came down to whoever had to make the decision as there's enough gray area to go either way.

That said, had the roles been reversed Russell would've complained all the way to the stewards to penalize Lawson. I'm not against Russell not getting a penalty but i would've found out far more satisfying if he did get a penalty.
