I passed two Sunlines today on I-75, both going the opposite way. The first was a '95 2370 and the second was a '80 13.5' RD, pulled by a '40s coupe hot rod. The car was smoking like crazy and left a huge smoke cloud all behind it, so I don't think it got too much further.
Farther down the road, a full size half ton conversion van passed us pulling a Flagstaff pop up. It was likely an original owner, in decent shape, and I'd say was about a 2000-2001 or so. Just as it got passed us, I noticed the left rear stab jack was down about half way, which seemed weird that it hadn't been ripped off at some previous point. Maybe it vibrated down. Then I noticed the left tire was looking a little low. Almost as soon as my brain processed that, the tire blew out while they were only a car length or two ahead of us. A woman was driving the van with what looked like the rest of the family asleep in the van. The whole back half of the van was packed with duffel bags, etc, where it looked to be impossible to see out. She was completely clueless about the tire, but since she was rolling at over 80 mph, no one could catch up to her to alert her. Finally, someone did, but she kept rolling at about 80. I google mapped the point where it blew to the exit that she finally got off on (at full speed, mind you), and she drove on it for a little more than 7 miles. It wasn't the real small and wide style, but it was the narrower, taller style tire, which fully disintegrated within the first half mile of blowing. I wish I had a video of the blow though, because it literally blew apart in the beginning and little pieces of rubber flew all over.
