The second thought i had watching this is about the drag reduction. Everyone is speaking whether drag reduction will be enough to make a pass into the first corner, where i believe it has been set for in the first 3 races, but watching these highlights it may have a much bigger effect on the corners that follow. In the highlights all passes were either made at corner 1 or 3. If drag reduction can only get a driver close at corner 1 when we go to monza, assuming that is where it is used, then they will be in a great position for corner 3 because they be closer enough to get a great slipstream on the run up to it.
Looking at Australia, this could be exactly the same for corners 1 and 3 there. As long as a driver can get close and stay there through corner 1 an 2, there will be a second opportunity with the long run to corner 3 with a good slipstream. Don't know if this has been mentioned before but could be very interesting.
