The driver of this vehicle was driving very slowly, leaving ridicules gap in traffic ahead, at least 6+ car spaces long in peak evening traffic which was very frustrating. Wasn't confident while entering the roundabout and whiles on it, they also switched lanes twice on the same roundabout causing traffic, confusion and a potential accident. I don't know who passed your driving test, but they surly were too generous putting it lightly. I think you should take a few more lesson.
"You don't pay Road Tax so not entitled to use the road!"
By your own measure, neither are you and a whole host of OTHER VEHICLES! Look it up!! The roads weren't made for your personal laws based upon your misguided and dangerous false sense of entitlement!
