One of the funniest things thats ever happened to me while driving. I was with a friend and I was passing by a road that was closed off because of minor construction so there wasnt any orange barrels or anything but they had cones and a road closed sign. I wasnt paying attention to where I was in relation to it and my cell phone dropped and i reached down to get it from the passenger seat floor and i slightly veered to the side. Not enough to like take out a sign or the curb or something but just enough to run over a cone. The cone got knocked around backward and made this grinding/thumping sound as it went under my car (not a pleasant sound might I add) and I immedietly looked into my rearview to see where it had come out... but it wasnt there. It was then I realized i was dragging it and it had gotten caught on the lip of my rear bumper.
About a mile later it finally decided to detatch itself from my bumper on a turn.... in the middle of an intersection... so as i drove off I heard people honking and i could see in my rearview people driving around a cone in the middle of the lane in the i-sect. Funny to me... probably not to the people I dropped it off in front of though
