Bill Nye, once known as "The Science Guy" thanks to his incredibly successful TV series of the same name, thinks the U.S. "should be embarrassed" at its lack of a high-speed rail system.During an interview with the Orlando Sentinel, Nye claimed hyperbolically that "every other country in the world" had high-speed rail, before explaining his belief that it was a development the United States had failed to replicate due to the "political" problems surrounding the issue."If I may, you should be embarrassed," Nye said.
