Trying to read the small print whilst driving sounds like a certain accident.
Agreed, and on most circuits where the corners are left and right and in quicker succession, you will see a car in your mirrors more often and they will normally have to fall in behind to get on the racing line.
Yesterday at Monza10k, I didn't know if I was clear when I often was, and had to take a tighter line, as Evil said, slowing down the pace of the group.
