Hi i drive for Royal Mail, have noticed in last 6months or so that at least 70% of all drivers (from HGV to cars) do not bother to indicat, does not matter if they are changing lanes on motorway, driving round or leaving a roundabout etc, my fav is when im driving along a main road in a town and the car in front puts its brakes on stops then turns right into a side street!! If you are a driver who does not use your indicators is it cause you are thick or bone lazy!!
