This inverted ‘U’ shape is a portion of a divider between parking spaces at my second most frequented parking lot. I like this kind of spacer better than the single lines that delineate spaces for cars. Being outside the limits of this double-lined spacer is assurance that one is parked correctly. One cannot be sure with the single-line-defined spaces. With nonstandard parking space widths, a comfortable space between the driver’s door and the line does not always translate to equal space on the other side of the vehicle.
Even at night, I am comfortable with this parking space divider.
