I had an interesting experience today. I was riding on the interstate in the middle lane. Traffic was not unusually heavy, suddenly I noticed an object airborne from the inside lane, it was the bed liner from a pick-up truck. The bed liner struck the car directly in front of me, bounced off that car and was thrown into the next lane hat a car and then was hit by a 3rd car. I made it past the bed liner and watched in my mirror as it was hit by the cars behind me. Had I not been paying attention I could have had a very serious accident.
