Take That Lane
This is just what it sounds like. Taking your place in the middle of a lane because it's unsafe at the edge of it. This is mostly done on streets where the traffic lanes are not very wide, so it's not safe for you and a car to be side-by-side.
This one is tough. Yes, cyclists are legally vehicles and allowed to occupy a full lane, but try and tell that to a driver on a two lane, two way street. I do my best to avoid such streets; I may have the right to be there, but it is a scary place to be.
