I’m pretty sure no-one is saying it’s Hamilton’s fault
The stewards actually did. They said that Lewis could’ve avoided the collision, but chose to turn in. Max was fully locked at that point, so couldn’t then avoid the collision. Had Max braked earlier, Lewis wouldn’t have had to avoid a collision. Racing incident as both did something that had they not done, would’ve avoided a collision.
Lewis wasn’t taking about his steering into the corner, He was talking about moving under braking, which he didn’t do. once he was slowed down, he turned into the corner. That’s allowed, but had he turned just a little later, he could have avoided the collision.
