I did my bus licence in 2006 and had to do the full test. All the spy in the cab questions and the like. The Hazard Perception test was a pig. Once you know what they are looking for it is fine, but as an experienced driver you see hazards that the learner is not expected to react to. Both our instructors took a mock test, when it was first being introduced, and both would have failed!.
Yes, today I followed an X3 and an X5, in convoy (both black), through the town. Seven roundabouts and not a signal from either of them. The X5 even made a right turn into a side street, right in front of me, without a signal. Just brakes on at the last minute and turn. I should post my dashcam footage on YouTube, number plates and all.
