It's nothing more than the law of averages...the RV industry has rebounded from the 2008 recession into the highest sales period EVER in the history of the industry. Here on LI you can't hardly get a campsite, it seems like every third house has an RV in the driveway.
So more RVs on the road means more RV wrecks, just that simple. I love that folks have to add their social commentary about how the younger generation (anybody not retired yet) is taking the country to heck in a handbasket.
