BTW, I realised today that for UK driver it's evern harder.. because well, considering you use the camera with the right hand, the left is to be used for the gearchanges... for us it's slightly better.. the same hand is for gears and camera.. so when I need to shit I can do it with the camera or put down the camera a second, change and take it again while at least one hand is always ready on the steering wheel
