The Blue Peter roundabout at Alvaston, Derby.

This is the Blue Peter Roundabout at Alvaston, Derby. I have heard many arguments about which lane should be used to turn left from Harvey Road into Shardlow Road by the bus stop. It is common for cars to start the left turn manoeuvre in the left hand lane, and then go straight out to the middle lane causing a near miss. I've indicated a logical route through the lanes at that point with coloured dots.
