Clark traffic circle - specifically the left turn to get onto Central Ave from the middle of the circle. There’s 2 left turn lanes, but only one (in the middle) takes you to Central Ave; the leftmost one brings you back around the circle. Like 95% of the cars in the leftmost one will cut you off under the bridge so they can get onto Central Ave. Its so dangerous and so predictable but it’s been like a decade and no one has done anything about it.
