The Dutch fixed the two-lane roundabout
On a normal two-lane roundabout, the inside lane can only get out by crossing the outside one.
From the video's description
Red or blue? On a normal two-lane roundabout, the inside lane can only get out by crossing the outside one. The Dutch turbo roundabout fixes that: you pick your lane before you go in, a low bump between the lanes keeps you in it, and your lane curves out to your exit.
