Apparently, this is a thing.
I got stuck on I-95 South this morning trying to get into work. It turned out that an RV fire closed down all southbound lanes for a bit. The cascading effect essentially made it impossible to get to the office.
I went to Google News to get details about the incident, finding the notion of a recreational vehicle spontaneously catching fire on a major interstate highway—when it’s cold and raining, to boot—unusual. Apparently, not so much. There are 1220 reports just for “RV fire I-95”—none of them about today’s incident. One wonders why they’re allowed to be on the road at all if they’re that flammable.
