The U.S. Transportation Department sees positives in so-called "talking car" technology, but it was only a few months ago that another government entity was warning of potential roadblocks up ahead.
According to the U.S. Department of Transportation, vehicle-to-vehicle technologies the Department wants to see in new vehicles will help prevent accidents, as vehicles will be able to detect other surrounding vehicles and their rate of speed.
In November 2013, the Government Accountability Office (GAO) suggested these technologies are expected to offer safety benefits but "a variety of deployment challenges exist."
Examples include whether a driver would respond appropriately to warnings of potential collisions and the need for a national communication security system to ensure trust in data transmitted among vehicles.
"I think the biggest challenges related to the security systems necessary to protect the data that's being shared, and a related challenge to that is who would pay for that," says Marc Scribner of the Competitive Enterprise Institute.
If it is comes down to state departments of transportation, Scribner says many of those agencies are "strapped for cash," and building the infrastructure – however long that could take – could take away resources that would otherwise be directed to repairs or maintenance.
Meanwhile, U.S. DOT officials plan to issue the proposal for a rule before President Obama leaves office in 2017.
