California debuts 'turbo roundabout' to fix troubled intersection near Bay Area

Its a Dutch invention. We have tons of them here everywhere. Think they got introduced somewhere at the end of the 20th century.

Found a good video explaining it, makes sense, for 3 lanes, you pick and stay in your lane (has a barrier)

* right lane for right turn

* middle lane for straight or right

* left lane for straight or left
