In August 2014 NHTSA published a report arguing vehicle-to-vehicle technology was technically proven as ready for deployment.[8] In April 2014 it was reported that U.S. regulators were close to approving V2V standards for the U.S. market.[9] On 20 August 2014 the NHTSA published an Advance Notice of Proposed Rulemaking (ANPRM) in the Federal Register,[10] arguing that the safety benefits of V2X communication could only be achieved, if a significant part of the vehicles fleet was equipped. Because of the lacking immediate benefit for early adopters the NHTSA proposed a mandatory introduction. On 25 June 2015 the US House of Representatives held a hearing on the matter, where again the NHTSA, as well as other stakeholders argued the case for V2X.[11]
