2) I assume you're from the US - you're really freaked out by roundabouts :) It's just a type of intersection like any another, in Europe or the Middle East no one cares and they're everywhere.
Left-turns on classic intersections (without separate light for turning) are the most dangerous, passing a roundabout is safe. Even if there's a collision on a roundabout, there are no fatalities due to the relatively slow speed and no significant difference of speed between vehicles, while a left-turn collision can be deadly or at least most of them are very destructive.

Seems like a nice idea, but it wouldn't work well with
1) Traffic lights
2) Roundabouts
3) Yield/stop signs
I imagine they are only intended be used on limited-access highways, where you don't have any of those things.

That wasn't my point. I know they are safe. But you have to yield, and that breaks the "train".
