FLATLANDS - Flatlands residents say speeding cars pose a danger in the neighborhood.

News 12 Brooklyn, using a radar gun, clocked cars going at 50 mph, 44 mph and 41 mph on Avenue L, where the speed limit is 30 miles per hour.

Residents say Avenue L is a one-way street, but has three lanes, which gives cars plenty of room to turn a residential street into a freeway.
