How to use a roundabout

[TomK]

"optimal use of a roundabout is possible if people indicate correctly; indicate LEFT if you are not exiting at the next exit and RIGHT if you are leaving at the next exit"

Drivers using their turn signals correctly is incredibly useful to others using a roundabout. It was drummed into me as a kid. Not only is it helpful to others and reduces congestion, it's simply a considerate thing to do (as it is any time you make a turn or change lane).

Unfortunately, I don't think it'll happen here given my experience.
