The law isn't new, but the final rule is new. As per the Wikipedia article you reference: > In January 2015, the NHTSA rescheduled the date for a final ruling to the end of 2015. Since the regulation comes into force three years after being rendered as a final rule, compliance was delayed to 2018. ... A final ruling was delayed at least until mid-March 2016. Sounds like an update is in order; the rule is finally final and compliance is now + 3 years = 2019.
