I live in a no stoplight town in WV. For the past few months, I've been seeing cars that are covered in cloth covers with all kinds of colors and designs to hide the shape and identity of the car. This is on 2 lane highways going north and south and east and west. I want to guess they are GM cars maybe Cadillacs. Can't say why but got that impression. They could be anything. Saw two the other day on the same road several cars and minutes between. I know they test new models out in the real world but in rural northeastern WV on 2 lane roads? Anybody else see this regularly?
