Eating, shaving (electric shaver), fooling with the dash, arguing with passengers, texting, surfing the web and recently talking on a cell phone using a hands free device and looking BELOW the steering wheel. I was stopped on a trail at an intersection and saw some dude coming up slow in a convertable, I didn't see and acknowledgment of my presence so I decided to wait on him, he pulled up and half way through the intersection talking loudly on a hands free cell phone device in the car, I could hear BOTH sides of the conversation. He pulled WAY past the white stop strip and was literally half way across the intersection, stopped and stayed there continuing to talk on the phone. Each time he talked he looked up, each time he listened he looked down, and the last time he listened he sailed halfway through the intersection. I elected to not say anything, waiting to make sure he wasn't going to back up on my a scooted across behind him. I heard some honking and yelling as I rode on, never looked back to see what happened.
