I've seen a number of pedestrians trying to cross, mid block, planning to dart out between cars. I yell, as a combination warning/magic spell, "Do NOT walk in front of me! Do NOT walk in front of me!" It gets their attention, and may work as a command, as well! Some snotty little teenagers decided to amble out anyway, and I yelled, "YOU DON'T WANT TO DO IT!" They stopped. Sometimes I just yell, "DON'T DO IT!", usually at cars wanting to turn left in front of me. I've also taken to waving my right arm up in the air to alert them to my presence.

It's a tight spot, the little lane where I ride between traffic and parked cars. If I jerk (or fall) to the left, there's an excellent chance of getting hit/run over. To the right, I'll collide with a parked car. If you walk out in front of me, I'll collide with you!
