drivers who slow down by 15 or so mph when oncomming traffic appears on a perfectly good 2 lane road.
drivers who go from 55 to 30 mph going past truvelo's and gatso's on national speed limit (60mph) roads.
drivers who do 30 or more mph through villages when it's school chucking out time.
drivers who overtake you and then slow down to less than you were going.
drivers who don;t realise that gravity makes them go slower on hills.
smugness
