And I bet you didn't bother to read the rest of the the thread where I already answered your question in a reply to someone else. In case you're too lazy to find it, I'll answer you directly: No, I don't tailgate. It is quite possible for one to be following a vehicle with the requisite space between or more, and be impacted by wintertime debris flying of the front vehicle and striking yours. Obviously this has never happened to you...or you'd have a clue.
It was winter and there was a lot of snow and ice on the ground...thus I couldn't slam on the brakes.
The tire debris lifted into the air ABOVE the trailer rig and came down just in time to wreck my front spoiler and fog light (BMW M3).
I would imagine ice and snow sheets would not have sailed like a 5 ft. piece of rubber...but your point is well taken.
Cheers!
