The cap on my side mirror decided to fly off while I was driving this morning. I had my car wrapped last year, so thankfully a corner of the wrap that wasn't tacked down right kept the thing attached to my car long enough for me to pull to the side of the road before it flew away completely. Just surprised the heck out of me that driving under normal conditions would cause this thing to just fly right off. Putting it back on took a few minutes...didn't seem to "snap" back in place easily. Even now that I think I've gotten it on right...I'm paranoid it's going to run away again since it doesn't feel very secure at all. Now since the car has been wrapped, that mirror cap has been removed in the past, but that was almost a year ago so if they didn't put it back on properly...it would have come off long ago.
