Roundabout fail

Union-Tribune:

Traffic statistics for the only two roundabouts installed so far along old Highway 101 in North County indicate the devices may be causing more problems than they solve.

Collisions have skyrocketed at a roundabout finished in 2014 near Carlsbad’s border with Oceanside, where the historic highway, known locally as Carlsbad Boulevard, intersects with State Street. After fewer than one collision annually before the installation, 15 collisions were reported in the five years from 2015 through 2019. There were 28 collisions in 2020 through 2024.

Also performing poorly is a roundabout completed in July 2022 in Encinitas, where the old thoroughfare is called North Coast Highway 101. That intersection with El Portal Street recorded just one collision in the 11 years prior to the installation. Since then there have been at least 17 collisions, making it the most hazardous intersection in the city.

To be fair, a lot of the crashes are single-car drunks and speeders, and it's arguably a good thing to decommission their vehicles before they hurt somebody.
