"If your car is a model from this century, there's a fair chance you do indeed, have a black box fitted somewhere within it. Black boxes have been in some of the major American car brands, like Buick, Chevy and Cadillac, since all the way back to 1994. The National Highway Traffic Safety Administration has been using them to collect car accident data since early in the 2000s. If your car is from 2013 or later, you are almost guaranteed to have a black box. Less than 5 percent of new cars came without one in 2013, and they are mandated in all new vehicles since 2014."
