Is that cause or effect, though? The environment is hostile to cyclists, so do you only get those who will be as hostile as they need to be in return to survive?
I work as a messenger and yes - the way to avoid being turned into (the main issue, if you are on the inside of someone who can't see you or someone doesn't signal) is to push in front of and into the flow of traffic. I have no doubt that it is concerning and annoying to drivers, but they have then seen me.
