I had an 84 Laser with a rear window louver. The hinge glued to the glass. one day I heard a noise driving up 95 and I saw some plastic hit the tractor trailer behind me. I thought I must have run over something. About 5 miles further I realized it was the louver had come off my car. It was only plastic and hit the truck behind me so I do not think it did any damage. By the time I realized it was my louver the truck was not around me anymore. I stopped but I guess he either had already passed me or had taken an exit. For a couple days I thought I might get a call from the police if someone had taken my tag number. Nothing ever came of it so I guess no harm, no foul.DSW said:........... i would hate to be on the freeway and have it fly off hitting the car behind me!!!!!!!!!!!! how well ban sticky pads hold up under those conditions
