There's a pretty dangerous left turn by where I live. Rather than people coming out of a shopping center and making a right, going to the light, and U-turning, they try to slingshot across 3 lanes of traffic, a center divider with trees, into a 4th lane. It even has a slight curve, making it even harder to see cars.

I've lived here for 7 years, and the only accidents I've ever seen on this road are at that point. I've no clue why they allow it to be the way it is. There's basically no safe way to make this left turn.
