I think Lando is getting a little too much stick for this .

Sure , he misjudged it , but not by that much , as within the next second he would have expected Oscar to move right to take a line a little closer to the racing line , or he wouldn't have made that first tight left .
Another point I think shouldn't be missed here is that Oscar wasn't tight to the side of the track , so a small amount of blame (very small , I admit) might be apportioned to him for leaving an enticing three quarters of a car width for a desperate team-mate to dive for .
A completely closed door might have avoided the clash completely .

I was well impressed with Lando taking responsibility right away .
That's what I expect from him , but I hope he sees it as as small an error as it was .
