For Verstappen entering right hander with excessive speed with a car under control, he had to end up with him gravitating towards outer edge, regardless how much space he had on his right, and it was inevitable that at some point he will cross path with Leclerc. Whether he should bear some or all responsibility for it is the question stewards should be looking at.
I think he should be responsible for his driving. That diving off his into turns without worrying about others is really questionable. He has done it to Vettel a few times already. Here he banged his wheels against Ferrari (I think 2x), which is another issue.
All those who defend Verstappen, try to substitute names like Hamilton in a red car, and Vettel (in RBR), and ask honestly yourself, whether you would be just as benevolent to Vettel, as you are to Verstappen. This might be a true test of your objectivity.
What's with Ferrari and Vettel? Bad strategy, bad tire, bad or rather botched pit stop, WTH?
