there are a lot of them about, I've lost count of the amount of people I've seen doing stupid things at the wheel.
people putting on make up while driving
lorry drivers reading a news paper on motorways is another common one, 40tons of lorry doing 56mph while the driver reads the sun always scares me when I see it!!
and the lorry speeds up, and slows down, speeds up, and slows down, speeds up, and slows down, speeds up, and slows down, speeds up, and slows down, speeds up, and slows down,
