In addition, I see that you snipped my #2, which I stated was even more
important than my #1: They were testing the*efficiency* of a roundabout

participants trained in order to eliminate the "What the heck do I do now?"
variable.

Real world efficiency assumes a real world population.

Then throw away the results every lab test done with rats, rabbits, pigs,
etc. None of those use a "real world population".

At least one new roundabout here usually becomes a 4 way stop with
added confusion.

For how long? Once the initial confusion passes, which type of intersection
is more efficient? That was the Mythbusters test: Which type of intersection
is more efficient? In a one-to-one comparison, with short-term variables
removed by a training period for both styles, the roundabout proved to be
more efficient.

In *my* real world experience, I have both roundabouts and 4 way stops in
my area. I typically have 4 roundabout experiences on a daily basis, a 4 way
stop experience at least twice a week. I lived through the construction of
the roundabouts so I have experienced/witnessed the learning curve for
myself.

I can unequivocally state that the roundabouts have been more efficient
during heavy traffic periods and an absolute joy when there is little to
no traffic.

They are better for our cars (less braking and accelerating) and better for
our environment (less idling as we inch towards the stop sign).

We are getting to the truth in a roundabout matter.
