Regardless of lane changing "best practices", I would never exit if there is a car to my right where I cannot safely exit from the left lane. Since there is no car to my right I can safely use whichever gate I wish.

There should never be a car to your right as you are exiting from the inside lane, unless they have entered the round about incorrectly. If they have done that I am not about to prove "I am right" by taking the exit in front of them.

PS. JMO, I feel much safer traversing a round-about than going through an intersection when the light is green. No one can kill me in a round about...
