Eating, drinking, smoking and even rolling the cigarettes on the wheel (when I smoked), talking to passengers, talking on the phone, sending sms (yes, that one can be a little tricky), taking pictures and videos (but not looking through the camera), using the computer while it’s on the passenger seat, reading a book (on the steering wheel) and writing notes. And yes, oral sex too, which was the most dangerous of all, and I stopped the car so we could do it properly (it’s the worst because you lose concentration, whereas with all the others you can still keep one eye on the road).
