This isn't necessarily the most annoying but its the wildest thing I saw a driver doing. We've all seen the putting on make up and shaving on the way to work in the morning, how about brushing their teeth. I saw a young guy brushing his teeth driving a Mustang on the Long Island Expressway. How is he rinsing his mouth and spitting it out? I wouldn't have believed it if I didn't see it with my own eyes. To me the most annoying thing is talking on cell phones while NOT using a hands free set (its illegal to use NON hands free phones in NY). Nobody obeys the law in NY. Police should be given permission to "shoot to kill all drivers NOT using a hands free set". Invariably they are in the left lane going 5 MPH, holding a phone in one hand and picking their nose with the other pay no attention to anything going on, on this planet. I've never seen such outright disregard for a law. You look at them when you see them talking and its like, what? The law doesn't apply to me does it? Thats my beef!
