heric : "People behind you to the left or right, who interpret your turn indicator as a signal that they must speed up quickly."

Those peolple would list me because, at the point of activating my signal, I have the right of way, and I take it. Of course, part of my boldness comes from driving an old pickup truck. I find those drivers you refer to are usually driving a sporty little import.

A fun tip (for daylight hours). After you change lanes and they are so irate that they weren't able to cut you off and decide to tailgate you in protest, turn on your lights and speed up at the same time.
