(TNS) -- The sight of self-driving cars has become nearly commonplace in Pittsburgh.
But in Arlington, Va., a van thought to be without a driver caused a bit of a hubbub.
"Half a man, half a car seat and a whole lot of questions that we had to answer," NBC 4 reporter Adam Tuss said in his report on the van.
Researchers at the Virginia Tech Transportation Institute wanted to see how people would react to a normal looking van without a driver in the front seat and if driverless cars needed to be clearly marked to avoid being a distraction. They dressed a man in a costume designed to look like the front seat of a van and drove around Arlington this week and last.
The news website ARLnow.com broke the story about the van. The site checked with Virginia Tech, Arlington County, the Arlington County Police Department, the Virginia Department of Transportation and the Federal Highway Administration for information but came up empty.
Tuss tried to talk to the "half man, half a car seat."

Virginia Tech Transportation Institute eventually told NBC 4 it was their van.
"They are testing it to get real world conditions," Tuss said in his report. "But, man this is one of the strangest stories I have ever covered, but we got to the bottom of it."

A Virginia Tech Technology Institute spokeswoman confirmed to the Tribune-Review it was the institute's study and said the results would be made public once the study is complete.
