DP says I am. But I hate when you are on a busy motorway, and someone is sitting in the middle lane, and will not move to the left hand lane, even though it is empty. While at the same time the right hand lane is packed with cars, making it hard to pull out into the right hand lane and still leave decent distances. So I have occasionally just overtaken the middle lane hogger in the left hand lane. I know the Highway Code says you should not, but sometimes it seems the safest option.
