I had one land on the front of my car and block my in car view for atleast 10 seconds on the Infinwhateveritscalled track, which is the reason why I couldn't see the one turn and went off the track. Thats my excuse, I mean, story, and i'm sticking too it.
I had a cone from this same spot land upright on top of my 787B and sit there for a couple seconds. Looked funny in the replay, I really should have taken a pic of it...
