I assumed he meant head-on drivers turning left across his path .... but once again, if you are in their way enough, they will often give up right of way, because the headaches of killing a cyclist ..... I mean, you have to call the police, and insurance and then sure, you get off with no charges because well, it was a just a bicyclist, and on the street, to boot .... but it might make you late for work, and in really extreme cases, you might scratch the paint or even crack a plastic bumper. Drivers avoid those things.
