The roads would be a safer place if no one indicated, ever.
Try pulling a fully laden HGV onto a roundabout where no-one is indicating. It warms my urine when I approach a roundabout, see a car on the roundabout heading in my direction (so I stop), which then turns left without indicating... Had I known it was turning left I could have kept going. Think of all that diesel being burned unnecessarily to get 44 tonnes of HGV moving from a standing start. I thought you cared about the environment Mr Drago? 😄.
My urine also heads towards boiling point when a car turns right at a roundabout without indicating, when I have pulled said HGV onto the roundabout assuming car was going straight on. Before I get blasted for making assumptions, in the scenarios I have given, at a busy roundabout, one has to make certain assumptions or you would sit there all day trying to get on the roundabout.
So please, for my sanity, use proper indications at roundabouts, including a left indication when leaving the roundabout. It helps us all get through the day!
@Drago , I assume that in your past life you were taught how to drive properly, a la system of car control?
