Here’s a link to one in WA state on I-5. The NVDOT just ‘installed’ a second one near us. They intersection was already a mess. Now a bigger mess. Especially during rush hour times.

It’s not the roundabouts.
That’s a symptom, not the cause.
The problem is that since law enforcement has decided to stop ticketing drivers for moving violations, roads have become Roman chariot race style free-for-alls. Including roundabouts
Enforce the damn traffic laws.
We’ll all be safer for it.
Since the day that mess in WA opened I have and will always avoid any business in that area. It used to be an OK place to travel through, but not any more.
