Crosswalks exist at intersections, marked or not. I've had at least two asshat drivers in the past week nearly run me over while crossing the street - in both cases they had STOPPED (looking for an opportunity to make a left turn) and proceeded to try to put on their gas again WHILE I WAS HALFWAY ACROSS THE ROAD. Seriously? WTF? I have the right of way and trying to run me over is not going to make me walk any faster.
