I actaully saw quite a few very impressive drive systems at the finals of the 3 regionals I attended: GLR, Midwest, and BMR.
Maybe I'm not too knowledgeable about drives, but I was really impressed with some of the contact action in a few matches, and the lengths robots went to protect goals and stop those crucial shots.
I think as the season develops, and individuals become more well-grounded in their understanding of penalties, there will be a lot more this interaction you're looking for.
