This looks like a joke a kid would've created in a city-building game.
The town of Hollister, California recently had the lines on its roads repainted . . . and they were looking to add stuff like bike lanes and "central circles" on the roads, because they wanted to slow traffic, and discourage street racing.
The roads were supposed to be slightly curved, but they turned out looking like zig-zagged, silly streets for a driving exam. The city says the contractor misread the plans, and they they'll be re-painted.
