Using a whole lane with 2+ lane roads
After being side swiped a few years ago, I now use a whole car lane as long as there are 2 or more lanes in the city. Between city blocks, I also move out of the lanes to let cars pass.
I have found that no matter how close I ride to the curb, there is not enough room for a car to safely pass without going into the next lane over, and many people don't understand how wide their cars really are. By riding too close to parked cars, I put myself in danger of getting doored.
The last few times I have ridden my bike in the city, I have had people honk at me and then deliberately pass me inches from their bumper. I normally just catch up with them at the next light and make them pass me again. These latest "brushes" have made me want to key a few cars, or at least make a bumper sticker saying I will.
What do others do when there aren't bike lanes?
