Yesterday, while out on a ride we were almost sideswiped by this moron in a mercedes who was yapping on her cell. SO at the stop light, my riding buddy yelled, "watch it, she's talking on her phone" and since her window was open, she heard him. I honestly thought she was drunk, at first, when I saw her weaving around. I suggested that from now on we be more colorful in these situations and say, "watch it, this idiot is yapping on her cell phone", perhaps shaming them into paying attention. Even if it doesn't work, it lets them know what you think of their driving.
