I was one of Max's biggest critics in 2018. I think that the worst spot was when he had the clash with Ocon. I remember Lewis said what I thought - just let him go since all he's doing is unlapping himself. You have to think big picture sometimes, which I think that Max does much better now in general.You can't look at the sample size of one race. If you do that, you might just as well take Germany 2019 and question Hamilton's maturity. I reckon Max made mistakes in the beginning of 2018, but I really can't think of any big streak of mistakes after that.
I think that, overall, Max is making much fewer mistakes than he once did. He is sometimes a bit too aggressive, which will likely be something he will always have to manage. But he has certainly no longer "Crashstappen" and I think that the Maldonado comparisons are dead now.
