u/-Exocet-

I once heard that France has the most roundabouts in the world, so I decided to verify it myself.

I pulled all roundabout locations from the OSM API and built this map.

Turns out it's true. France leads with over 141k roundabouts, which is around 14% of all roundabouts worldwide, followed by Spain with 120k.

Data available here: https://github.com/mickaelmarchese/round-abouts/blob/main/roundabouts.csv

EDIT : I made a mistake while calculating the number of roundabouts. I filtered OSM data on junction = 'roundabout'  but it appears that there are multiple junctions per actual roundabout, so I merged junctions less than 20m appart.

The revised numbers are :

• FR: 66 616 (12,6%)
• ES: 51 580 (9,8%)
• IT: 42 691 (8,1%)
