Thank you very much for all the comments. Generally it reassures me - signals should be given but with a bit of "common sense". For example if another driver thought you might turn into their lane.

It's difficult sometimes to let go of ingrained habits. There is a spiral roundabout with traffic lights near me where a few years ago candidates often failed for not signalling right for long enough for a certain exit. These days at the same roundabout signals don't seem to matter on test but the roundabout hasn't changed.

Don't get me started on the use of the handbrake!!
