Driving standards here are way better than some countries I've visited. I have also noticed highway management due to the demands of increased traffic volume has led to the need to change certain junctions etc. This also adds to the mix of incompetence on our roads. Take a roundabout for example, navigating a roundabout was once a simple affair. You would approach on a 6 o clock basis, a turn past your 12 o clock would be classed as a right turn and indication to follow suit, then a quick indication to the left just before your exit whilst checking the nearside mirror etc.
Due to increased traffic volume highways have been painting lanes on the roundabout and in some cases will mark the nearside lane as a right turn also. This confuses people who can't or won't read the signage or lane markings correctly. Also the very same people who are bereft of common sense then think it's ok to use the nearside lane to turn right on a normal unmarked roundabout. These types rarely indicate and if they do its for the exit they want rather than letting waiting vehicles know they are circumnavigating a right turn. The same applies for the knob heads who use a right lane to go straight on or before 12 when the exit is single carriageway not dual.
