Here is some very sad news.  Michael S. Rosenwald and John Woodrow Cox report in the WaPo:

The Route 29 Batman, whose roadside encounter with Montgomery County police three years ago made him a viral sensation around the world, has died.

Lenny B. Robinson, the 51-year-old Maryland man who drove a custom-made Batmobile and dressed as the Caped Crusader to visit sick children in hospitals, was struck by a car on Interstate 70 on Sunday night near Hagerstown, Md., after the Batmobile broke down. He was coming home from a car show in West Virginia.
