The town is Bauné, near Angers, home to 1,700 people. But because of its location at the crossroads between two departmental roads, roughly 2,300 cars pass through Bauné and reach speeds of over 60 mph even though the town’s signs at the intersection demand far lower velocity. So in order to get drivers to slow down, some genius had the brainstorm of using the intentionally confounding road markings above, and local authorities agreed to adopt the strategy.
Confused drivers are slowing down, all right. Other effective solutions would have been having blinding strobe lights flashing at drivers or insult-spewing mimes throwing water balloons at windshields.
Here’s an aerial view of the mess:

Hawaii (the big island) is doing something similar on the approach to sidewalks. It isn’t as extreme but is confusing.
I just checked on Google maps at a location I specifically recall seeing it. It was a few blocks from where I stayed recently so I could be sure on the location, and it is not on the areal map. This must be a recent idea they’re trying.
The drivers will no doubt slow down yes but then what, now that they’re confused? Stop and think, attempt to reconcile the chaotic lines with all you ever learned as a native frog about driving in France? and get run over? French road rage, a La Salle D’Armes .357 under every deux chevaux’s -driver’s side- front seat. Reminds me of a roundabout in Ahmedabad, the traffic cop in white gloves and whistle dares not enter the intersection.
I’d hate to live in that house at the intersection. I suspect there will be a few unexpected visitors.

Never heard of speed bumps, apparently.
. . . or . . . you know . . . bypasses.

P.S. As a driver of a car with a lower-than-average road clearance, I **HATE** speed bumps.
One would think that the local government would choose to install speed cameras, and reap the windfall from speeding ticket fines. However, I’ve heard what the French do to speeding cameras. It’s not good for the health of the cameras.
