This Dale Earnhardt Jr. post to Twitter sort of speaks for itself.
All we can say is it's a great thing that Earnhardt came across the driver of this rather dirty vehicle with the unique message scrawled in the dust that was caked on the back window.
We can only assume that Dale Jr. and all other occupants in vehicles trailing kept a safe distance -- although 50 miles seemed a bit extreme and there was no room left for interpretation if the driver of the car trailing it actually was an Earnhardt.
