The objective of the owners of these cars is to make their cars look as stupid as possible. Forget about functionality or safety. You should see the cars around where I am, people buy Honda Civics, put one wiper on them, 18 inch rims and the loudest muffler manufactured in the world. When they modify these cars to be one wiper, they leave the same wiper motor and same size wiper blade, so there is a substantial decrease in visibility during the rain. Same thing with putting blue halogen bulbs on. There may be no light, but at least it's blue.
These guys just want to have an ugly, and truly unique car without spending much money on it.
