1. Don't block 2 lanes in a merge in turn because you 'don't like people overtaking you' is petty and doesn't help the flow of traffic.
2. Going 33mph on a single carriageway and deliberately blocking the flow of traffic, illegal.
3. Speed matching and closing down space when someone is trying to get in front of you to get away from you and your dangerous driving, just downright stupid.
