Not the way to stripe a parking lot

Sometimes a parking lot isn't sized correctly to fit exactly the right number of cars and trucks, so what does a smart designer do with the extra space? Plant trees? Create a special double-deep row for vehicles with trailers? Whatever the right answer is, the wrong answer is to just create a third row between two other rows and draw boxes around each of the spaces. It's bound to confuse anyone the first time they see it, and inevitably someone will end up making the mistake of parking in that "middle child" set of spaces and end up completely boxed-in. How about tearing out the extra row and planting a few trees for shade instead? Or shifting all of the rows over by 10 feet and creating an extra pull-in row (for buses and RVs) perpendicular to the rest at the edge of the lot?
