I thought that it could mean something else entirely. Duh.
I see a golf cart parking space on the opposite side of the street. I turn across the oncoming lane to park in that space. Now, when I leave that space, I back across the closest lane to go the opposite direction. I imagined that I was wrong backing across the lane to the farthest lane rather than backing out and going to the closest lane.
Thanks again. You can see how my mind is jumbled.
