Both racing incidents I would say, although you could make cases for both to say they weren't.
Vettel: Visibility wasn't so bad at that point, at only the fourth turn it's natural that the track is going to be crowded and taking the line he did, you cannot realistically expect nobody to be on the inside. He got away with it though and moving to the back of the field was probably penalty enough, regardless of moving swiftly back through. I cannot help but feel that if the situation was reversed, the radio contact and subsequent action may have been different.
Hulkenberg: Given the conditions, it wasn't the wisest thing to do, going in so hot. But there was obviously no intention to take Hamilton out, the back end kicking out is not done on purpose, but a more experienced driver would possibly have been more cautious.
